How the War Crates Flew: Bombs and Bombing

Link - Posted by David on October 5, 2022 @ 6:00 am in

FROM the pages of the February 1933 number of Sky Fighters:

Editor’s Note: We feel that this magazine has been exceedingly fortunate in securing R. Sidney Bowen to conduct a technical department each month. It is Mr. Bowen’s idea to tell us the underlying principles and facts concerning expressions and ideas of air-war terminology. Each month he will enlarge upon some particular statement in the stories of this magazine. Mr. Bowen is qualified for this work, not only because he was a war pilot of the Royal Air Force, but also because he has been the editor of one of the foremost technical journals of aviation.

Bombs and Bombing

by Robert Sidney Bowen (Sky Fighters,February 1933)

SIT down, you buzzards, and stay down! Any side remarks and I’ll. . . . Huh? What’s that? Why am I all steamed up? Well, just take a look at this letter. The darn thing explains itself.

Dear Uncle Wash-out:
    I think SKY FIGHTERS is a pretty swell magazine even if it does contain your stuff. But I’m just kidding about the last part. I guess you’ll do all right.
    However, here is a complaint. Wasn’t there anything else besides pursuit ships in the World War? Or were they the only ones you knew how to fly? Seems to me that I’ve read some slick yarns in this mag that had to do with bombing raids. Do you know anything about the technical side of bombing, or are you just plain dumb about that sort of thing?

Henry Craveil

Now, if Henry lived just across the street I’d sure step over and bend a couple of one hundred and twenty pound bombs over his dome. But he happens to live out in Oregon, and that’s too much of a walk for me. So I’ve just got to swallow that there insult, and try to fix Henry up the best I can. And while I’m doing it you other crash hounds can pin back your ears and get a brain full.

Yes, I’ve shoved a few bombers around in my day, and have dropped a couple of eggs here and there. Now don’t go asking me what I hit, because I promised the C.O. of this mag never to tell a lie, and I’m not going to break that promise just to maintain my glorious reputation with you birds.

But, shut up! Let’s get serious.

World War airplanes were divided into three general classes. They were pursuit planes, observation planes, and bombing planes. Of the three classes the pursuit ship was the only one that could perform all three functions. Now, when I say that, I don’t mean to imply that it was a waste of time to have observation ships and bombers in action. Naturally, each type of ship could perform its own particular job better than either of the other two. However, a pursuit ship could serve as a scouting plane, an observation plane, and also drop a total of about eighty to one hundred pounds of bombs. An observation plane could do its job of reconnaissance and drop bombs as well. And perhaps in a pinch serve as a pursuit ship. I say that because the well-known Bristol Fighter could outfly almost any pursuit ship, at least from the standpoint of speed. Another one, too, was the British DH9 powered with the Liberty or Rolls-Royce engine.

But for the sake of this chinfest we’ll say that the general run of observation ships were not good in pursuit work. The bombers, of course, were ships built for the job that the name implies—bombing. However, they could also function as observation ships, for the very plain reason that observing means seeing things with the eyes. And the crew of a bomber naturally didn’t fly with their eyes closed. However, no bomber in the World War could serve as a pursuit job, no matter how much cognac the pilot put under his belt.

LISTEN, buzzard, sit down! What?

What’s all this got to do with bomb dropping?

The answer is, nothing in particular. However, I’ve been using up breath with the idea of first pointing out how the particular job of each of the three general classes of ships used during the war overlapped each other. One of your favorite authors might tell of a pursuit job bombing a place. And you might say, “Horse-feathers! Bombers did that sort of thing!” So I’m just putting in a few words or two to save the authors’ hides. I passed out a couple of cracks at them at other chinfests, so I’ll get back in their good graces now by proving the authenticity of some of the stuff they write. Sure the emphasis is on the “some”! Think an honest war-chicken like me would back ‘em up in everything they said? Huh! I want to go to heaven sometime, you know!

Oh, yes, about bombs.

WELL, as I know, and you should know by now, an aerial bomb is, fundamentally speaking, a container full of high explosive that will detonate and explode when it comes in contact with the ground after its travel through the air. There are all kinds of sizes, shapes and mechanical functions of bombs. However, there are two features that are incorporated in any type of aerial bomb. One is to travel nose first, and the other, to detonate and explode upon contact with an object, or in the case of delayed detonation, to explode after the bomb has penetrated its objective.

In order that bombs will drop nose first, they are of course made heavier at the nose. In other words, pear shaped. To get the idea look at Fig. 1. Now, in order that the bomb will maintain directional stability (not wobble around, or go end over end) the bomb is fitted with rudders, or vanes as they are called. There may be three or four vanes, set equal distances apart at the rear end of the bomb, or I should say, the tail of the bomb. These vanes, when passing through the air, tend to keep the bomb going straight, just as the feathered vanes at the end of an arrow keep the arrow to a straight path of travel. See Fig. 2.

THERE are various ways to make a bomb explode once it strikes its objective. There are, generally speaking, certain types of bombs that have the detonator in the nose. Others have it in the tail. And still others have a detonator in both the nose and tail.

Now, of course, it is not a good idea to have bombs all set to explode when in the bomb racks of your ship. In other words they should be fitted with some sort of a safety device that will keep them from detonating themselves until they have struck the objective. Of the type of bomb I’m talking about (which was used quite generally during the war) there were two kinds of safety devices. The first was a safety pin that had to be yanked out before the detonator could strike the explosive. An idea of this safety pin can be obtained from Fig. 3. Just as in a hand grenade there was a pin that had to be pulled out before you threw the grenade.

The other safety device was a little propeller attached to the end of the detonator. If the fuse was at the tail of the bomb and the bomb exploded by the detonator traveling downward, the detonator rod was threaded so that the little propeller revolving in the air stream would eventually spin free of the rod and allow the detonator to snap down when the bomb
struck. In case you birds are still dumb about that point, take a look at Fig. 4.

Naturally, if the detonator was in the nose the little propeller was fastened to the detonator so that the air stream would spin it around and allow the detonator to move up where it could hit the fuse when the bomb struck, as in Fig. 5. And, of course, you can figure for yourself how the propellers would be set in relation to the detonating pins when-there was a detonator at each end of the bomb.

NOW, just to clear up those two safety devices, let me say that the little propellers do not function until the bomb is traveling through the air, after it has left the ship.

Yes, yes, I know. Why didn’t the little props untwist when the bomb was going through the air and still attached to the bomb rack?

Well, smarty, because there was a second pin, attached to the bomb-rack, that stuck between the little prop blades and thus stopped them from revolving. And the first safety pin that I spoke about, that passed straight through the detonating rod and prevented it from moving, even though the props were off, was also attached to the bomb-rack. So you see, when the bomb was released both safety pins were pulled loose (or rather, the bomb pulled loose from the safety pins) and the bomb went sailing down with its little props spinning, so that the detonators could do their stuff when the bombs struck.

THERE is no need of going into the explosive side of bombs. Different combinations of chemicals and powders made different kinds of explosives. We won’t try to give you a talk on chemistry today. However, there is one point I want to speak of—that’s the item of delayed explosions. For instance, if you are bombing troops and other things on the surface of the ground, you want a bomb that will explode instantly and hurl its death dealing messengers in all directions. But if the bomb must first go through armament, etc., before it can do any worthwhile damage, you naturally have got to have a bomb that will explode after contact. It’s the same principle as shells from artillery guns. And its worked out by a system of delayed fusing. In other words the bomb strikes, the detonator hits the fuse, but the main body of the explosive does not go off instantly. Of course you must realize that when I speak of a delayed explosion I don’t mean an explosion that comes five or ten minutes after the bomb strikes. A delay of one quarter of a second is long enough.

Now, just one more thing before we talk about actual bombing. The bombs that we are chinning about now are aerial bombs that are used for destructive purposes. In short, bombs that will blow the pants off your enemy, and him along with them. But, of course, there are other kinds of aerial bombs. One is the parachute bomb that you release so that it will strike and light up the surrounding country in case you are making a night landing. And the other type is the flare bomb that is used for signalling purposes. Both types arc more or less electrically operated. In other words the bomb is ignited as it passes through the air.

Like many other functions of airplanes, bombing is often all planned out ahead of time. That is, bombing of a certain objective by bombing planes. Let us say that Brigade has issued an order to a bombing squadron to try and knock the daylights out of a railhead back of the enemy lines. The first thing to figure out is what types of bombs to use. In other words instantaneous or delayed action bombs. Then comes the selection of the time to make the raid (whether daylight or at night) and how many planes to use.

NATURALLY the bombers must have a pursuit escort. Some scrapping ships to keep away the enemy should he stick his nose in and try to upset the apple cart. That, of course, is arranged by Brigade. The pursuit ships will meet the bombers at a predetermined point, escort them over, and escort them back—we hope!

Now, it must be figured out before hand, as near as possible, just how the bombing is to be done. Shall it be one ship at a time, or all at once. However, no matter what Is decided, the accuracy of dropping the bombs depends upon the speed of your plane, your altitude and the direction of the wind. By plotting those three items you can set your bomb sight so that you will have a fair chance of hitting your objective. Bomb sights of today have been worked out so that they are pretty accurate. In the late war they weren’t so good, although the boys did a darn fine job with what they had.

SOME of you buzzards think that all a bomber does is fly over its target and drop a bomb, and fly away. That’s all wrong. A bomb is released before you reach the target. And if you have set your bomb sight correctly the bomb strikes the target when the plane is directly over said target. See Fig. 6.

You ask why, eh? Well here’s why.

The plane is traveling through the air. That means that every part of the plane has a certain amount of momentum. In other words, anything that leaves the plane travels forward a certain distance before gravity can take full charge. Naturally, gravity has its effect the instant the bomb is released, but it takes full charge gradually so the downward path of the bomb is curved. (As shown in Fig. 6.) Therefore the bomb must be released before the target is reached, as it travels forward as it travels downward.

Now, if the plane is traveling into the wind its actual ground speed is reduced, though, of course, air speed (the speed at which the wings pass through the air) is constant. It follows then that when the bomb is released its forward travel will also be reduced by wind resistance, and it must therefore be released when the plane is closer to the target, than it would be if the plane was flying with the wind. Naturally when the wind speed is estimated and calculated, the altitude at which to fly is then determined. Or rather the best altitude at which to fly. In other words if it takes eight seconds for your bomb to drop from a bombing altitude of 1000 feet and your plane travels ground speed at the rate of two thousand feet in eight seconds, you must set your bomb sight so that the target will be in the “finder” (center of the sight) when you are two thousand feet away from the target. To sum it all up, you estimate wind speed and direction, then set your sight in accordance with the number of seconds it will take the bomb to drop from a stipulated altitude. Then you bomb from that altitude. And if you wipe out the objective, maybe we’ll give you a medal!

THE releasing of a bomb is simple. As the nose must drop first, the bomb is put in the rack, nose forward. It is gripped by what are called “toggles” at the nose and the tail. By pulling the toggle release, which is simply a lever in the cockpit with a wire leading down to the toggle catches, the catches are opened and the weight of the bomb itself makes it drop free. Some planes had individual bomb-racks under the wings. Each bomb could be released separately or all the whole works at once. The big bombers had vertical racks. In other words the bombs were placed one upon the other. When the lowest one was released, the one above it automatically dropped into the lowest one’s place.

Bombing by bombers and some observation ships was an art all its own. In pursuit ships bombing was a hit-and-miss affair. First, you oniy had about twenty pound bombs. Just enough for “surface” damage, such as in trench straffing. Second, you had no sights (though modern pursuit ships have bomb sights). And third, you often released your bombs on pursuit ships without any idea of hitting anything. That was, of course, when some enemy pursuit ships I jumped on you, and you wanted to reduce the weight of your ship, and thus increase its maneuverability qualities.

So there, Henry, you insulting buzzard, is some dope on bombs and bombing. And by the look in the C.O.’s eye I think he’s about set to drop an egg on your Uncle Wash-Out—so consider me gone!!

“Rickenbacker Downs Two” by Paul Bissell

THIS week we present another of Paul Bissell’s covers for Flying Aces! Bissell is mainly known for doing the covers of Flying Aces from 1931 through 1934 when C.B. Mayshark took over duties. For the February 1933 cover Bissell put us right in the action as

Rickenbacker Downs Two

th_FA_3302“Sure he can fly, I’ll hand him that. But what’s the idea of making us hang around on the ground? We don’t come to this flyin’ school nowadays to watch exhibition flyin’.”

“Oh, well, some guys get all the gravy,” and the speaker petulantly kicked a hole in the turf of the flying field. “Probably he’s somebody’s bright boy whose daddy gave him his own plane. Pretty soft, I call it. What do you say, Sarge?”

The man thus addressed was much older than the students and was evidently in charge of them. He was a hard-bitten mechanician and evidently an ex-army man.

“Soft!” he exclaimed scornfully. “You damned babies make me sick. Say, don’t you know who that guy was?”

“I don’t see that it matters a damn who he was,” spoke up one youngster. “We’re here to learn to fly and—”

“Oh, you don’t, don’t you?” and this time the sergeant’s voice was hard. “Well, get this, youngster. There are certain men who’ve done things for their country that you can’t pay for in dollars and cents, see? You—and I mean everybody in the country—can just try to give them a little courtesy and special treatment whenever you get a chance to, and be damned glad for the chance.

“If we was in the army, you know what I’d ’a’ done, don’t you? I’d ‘a’ marched every damned one of you out on that field and kept you at attention the whole time he was here so that the next time you’d know a good man when you saw him. Say, don’t you guys know who that feller was?” The sergeant’s tone was one of complete exasperation that such ignorance could exist.

“No? Then listen, buzzards. I’m goin’ to tell you a true bedtime story. Once upon a time when you babies were still wearing didies there was a war. Maybe you never heard of it, what with peace societies and all those sort of things these days, but, everything considered, it was quite a little war at that. Now I was sort of young and foolish about then, and seeing a nice poster displayed ’bout how you could join the air service and learn to fly, I goes in and lets them take my fingerprints. I guess that was a mistake. They must’ve read my palm or something at the same time and decided I was an advance model of you birds and never would learn to fly, so they didn’t even try to teach me. But anyway, they sent me over with a squadron to see that the Frogs didn’t get any vin rouge by mistake into the gas tanks ’stead o’ gas.

“The outfit I finally pulls up with was the 94th Squadron. I s’pose you ain’t never heard of the 94th, eh? Guess they just omitted mentionin’ that at your schools. Well, believe me, the Germans knew about the 94th, and when they saw a ship with old Uncle Sam’s hat with a ring around it painted on the sides, they knew that hell was going to be poppin’ loose in just about a minute. That was the first real Yank squadron to cross the Front. Ninety-one Germans they got before the show was over. Americans, every damned one in the 94th. And the guy that just went off in that limousine was the boy that led them through the last lap.

“PRETTY soft, you said, didn’t you, Buck?” And he spat scornfully to one side as he squinted at the embarrassed youngster in front of him. “Well, it wasn’t always soft. Once before I saw him come out on the field, sort of like today, only dif’rent. He was a captain then, and it wasn’t a limousine, but a damned poor motorcycle and side-car, with the corporal sittin’ in the side-car, holding on like he was in a rollercoaster, and the captain tearin’ across the field like he was tryin’ to hang up another speed record.

“It was the day he took charge of the squadron, and he was just hell bent to get up and get himself a Boche. We were just outside of Toul then, and the Germans were damned fresh in that sector, so he didn’t have to look very hard before he located two observation crates quietly gettin’ in their work with five Fokkers playin’ nurse to ’em up in the clouds. Right then the captain started climbin’. The old game—up into the sun.

“Maybe they would see him, and then maybe—well, anyway they didn’t. And he got just where he wanted to, sittin’ up on the last German’s tail with the sun square behind him.

“You ain’t ever seen a Spad dive, buddies, have you? Well, we used to call them the ‘flyin’ bricks’ over there, and when you turn one over on its nose and give her the gun, she moves so fast she damn near catches up with the bullets out of her own guns. And that’s the way the captain went down at that first German. The poor Fritzie didn’t have a chance. Here was the captain lettin’ both guns go, and comin’ down right behind the bullets themselves.

“The bullets must’ve beat the Spad a little, at that, ’cause the Fokker started spoutin’ smoke and slipped off sort of cockeyed, headin’ for the ground, just as the captain and his Spad dived by and right through the whole formation. Then a zoom, and he was back above them again, hangin’ on his prop, lookin’ them over. Fritzie must’ve thought there was another dozen or two comin’ behind him, because they got their wind up and broke.

“Quick as a flash the captain kicked his rudder over, shot his stick to neutral, and down he dropped like God’s judgment on the two L.V.G.s below. They saw him comin’, and the gunners were plenty ready for him, too. Hell’s bells, how they peppered him! I know, ’cause I helped to put the patches on when he got back. But none of those pills landed where it hurt, and before those Fritzies could turn or twist, he was past them, and zooming back for another crack at them.

“The other Jerries had got their nerve back by now and were divin’ in. It had to be a quick job, and the captain knew it. He slipped the bus off on a wing, and, holding her in the slip, slowly eased his nose around until he had both the two-seaters in range at the same instant. Then he cut loose, both guns pumpin’. You could see the tracers zippin’ through the air and buryin’ themselves in the Jerry machines.

“It was a queer spot the captain was in, and a couple of seconds was all he could hold it. But he had the Boche dead on the spot, and these seconds were plenty. The nearest ship tailed up and a couple of German aviators were just German heroes. The other Jerries seemed sort of discouraged, too. They weren’t crowdin’ any more, but had gone into a huddle around the photo-bus, and all were headin’ for the Vaterland.

“Gas and ammo were about out, so the captain came on in. Two minutes—two Germans. Not bad, eh? Well, he got twenty-five before that mess was over, and waded through a hundred bits of hell to get them.

“Soft!” The sergeant spat disgustedly into the dust again. “You birds weren’t close to him, were you? You didn’t see that little blue bar he wears with the silver stars on it? Well, you probably wouldn’t have recognized it, anyway. They ain’t many of them around. Maybe you don’t even know what it means—maybe you don’t know yet who the captain is. Well, remember this, ’cause after all, you’ve got to get over some o’ your dumbness and not be forever shootin’ off your mouth and showin’ your ignorance. That little blue bar is the Congressional Medal of Honor. Only two aviators in the whole war won it. One was Luke, the Balloon Buster. He’s dead, and can’t wear his. But the other man can, and he’s the guy that you birds called soft. He’s Eddie Rickenbacker, ex-captain of the Hat-in-the-Ring Squadron, and America’s ace of aces!”

Flying Aces, February 1933 by Paul J. Bissell

“Lives of the Aces in Pictures – Part 10: Captain Ball, British V.C.” by Eugene Frandzen

Link - Posted by David on March 16, 2016 @ 6:00 am in

Starting in the May 1932 issue of Flying Aces and running almost 4 years, Eugene Frandzen’s “Lives of the Aces in Pictures” was a staple of the magazine. Each month Frandzen would feature a different Ace that rose to fame during the Great War. This time around we have English Ace—Captain Albert Ball!

Captain Albert Ball was the first of the Royal Flying Corps pilots to make a distinguished record. Unlike the French, the British made no mention of their air pilot’s victories. One day Ball wrote home that he had just counted his 22nd victory. His mother proudly showed this letter to her friends. Ball was disbelieved.

It was beyond belief at that time that any single pilot could have shot down so many enemy planes. Ball was finally vindicated. From that time on the British publicized the exploits of flying aces. Ball shot down 43 enemy planes and one balloon, being at the time of his death the Ace of Aces of all the armies.

He received every decoration the British Army could give him, including the Victoria Cross. He was killed in a new British triplane by the younger von Richthofen the day after America entered the War.

(Editor’s Note: These early installments of Frandzen’s “Lives of the Aces in Pictures” that were published in the pulp-sized issues have been reformatted from a two page spread into a one page feature.)

Decoy Smashers

Link - Posted by David on September 18, 2014 @ 12:00 pm in

Frederick Blakeslee painted the covers for Dare-Devil Aces‘ entire fourteen year run. Every one of those covers told a story, and Blakeslee had a page with which to do so. We present Blakeslee’s cover for the February 1933 issue of Dare-Devil Aces—”Decoy Smashers”…

th_DDA_3302AN IMPORTANT offensive had been held up by the activities of a group of four German balloons, that, floating close together in a line, looked exactly alike. When a patrol was sent against them it was found that at least three of these balloons were decoys filled with H.E. Upon being attacked the balloons were all pulled down to lure the planes closer, and then they were exploded with frightful results. The first patrol was almost wiped out and a short time later four more balloons were floating in the same place.

After a day of careful observation it was still uncertain which balloon carried the observer. However, another group of fighting ships took off with a plan to trick the Germans into exploding all the decoys, after which the remaining balloon could be attacked. This patrol was driven off by superior numbers and the balloons remained.

It became a game to see who could outwit the other and the outcome was watched by every outfit in that sector. More than one pilot in a fast pursuit ship had a go at these balloons without any success. The sausages still held the sky and still held up the offensive. It remained for a comparatively slow bomber, totally unprotected and quite by accident, to discover and destroy the correct balloon.

A British pilot and observer had completed an important photographic mission into Germany. Returning they suddenly became aware that a strong force of the enemy were converging on them from three sides.

Only one way was open. This led directly over the four balloons. They sped for this opening, intent only on getting away with the photographs. As they flew over one of the balloons they saw an object drop from the basket and a moment later a parachute open. They knew then that this was the one balloon of the four that for days had held up the offensive. Turning quickly, the observer poured a deadly fire into the bag at close range. The sudden turn of the Bristol completely disorganized the pursuit and before the Germans could follow, the balloon was falling in flames and the Bristol was speeding to safety. Without giving the balloons time to be lowered and positions changed, troops went over the top, captured the position and so allowed the offensive to organize, and later secure a victory.

Did the two Englishmen receive medals from a grateful government? They did not! They were reprimanded for jeopardizing the safety of valuable photographs.
