described above. The first type (I.B.E.N.—Figures 12A and 12B) has a 3½ oz. charge and a total weight of 2.2 kg. which will cause the bomb to penetrate further into buildings than the ordinary type. The overall length without tail is 1 ft. 5 in. A stiff wire 13 in. long with metal disc about 1½ in. diameter at the upper end is passed through the ring at the end of the tail vanes down the side of the bomb and through a hole in a safety pin, projecting from the fuze body. On release from the aircraft air pressure withdraws the wire, which falls separately and may be found on the ground some distance from the bomb. The safety pin is then ejected by an internal spring leaving the striker free. On impact the fuze functions igniting the incendiary body immediately and lighting a slow match fuze in the nose, extending the delay before the detonation of the explosive charge up to a maximum of seven minutes. The explosive extension may also break off on impact and detonate separately, some distance from the incendiary body (Figure 12B). Some fireworks are deliberately designed to make a bomb whistle sound. The most common way to do this is to combine a special fuel with a partially empty combustion chamber. The empty space acts as a resonance chamber, and since it gets larger as the fuel burns, the pitch decreases over time. Note: 1-kg. incendiary bombs have also been found fixed to the vanes of a 50-kg. H.E. bomb by clips.) Peter - If the missile could fall under gravity further, accelerating all time, after falling about 5,000 metres it would reach the speed of sound and would then emit a sonic bomb, just as supersonic aircraft do when then fly at speeds greater than the speed of sound.

There was also a particular type of German warplane, called a Stuka, that was designed to make a piercing whistle whenever it went into a dive. This had the same effect as the falling bombs, but could last even longer, and would precede a strafing run or its own dropped payload of bombs. This sound is played in Heavy Weapon as soon as a bomb is dropped by any enemy aircraft. Yes, when the bomb comes out of the airplane, no less.

Inverted with the Doodlebugs of WWII. Their engines droned and propelled them forward constantly until their timers ran out. When they stopped making noise, you knew something nearby was about to blow up. Also inverted by their upgrade, the V2, which traveled faster than sound. If you heard it, you were fine. People who lived through the Blitz on London (1940-41, mostly) mention that falling bombs made a sound like a parcel sliding down a chute. c) A sheet metal collar may be welded to the case between the filling cap and the shoulder. The collar, which is often painted red, is drilled and tapped to take 8 screws. No naked light or lighted cigarette should be brought too near them otherwise the gas may ignite, or, in the case of larger balloons, cause an explosion. This device consists of a can 11 in. × 6 in. × 4 in., containing one gallon of incendiary jelly, and is slung beneath a canister of the type used in device (b). At one end of the can there is a releasing device mounted on a plate which slides on to the end of the can, and at the iv) Another small type enclosed in an alloy casing about 1 ft. 6 in.long and 3½ in. diameter, with a sheet steel cap at the upper end, and stamped in yellow or green lettering: "70 Eisfeld Dez" 1937 (see Figure 59).

The normal smoke float has a cylindrical body with drum tail, weighing 11 lb. It is 22 in. long and 6 in. diameter, and is painted green. The tail end is fitted with a pistol to fire the float. The smoke is poisonous in an enclosed space.Two types of infantry training bombs may be met—the 6 lb. and the 60 lb. Both are filled with a powerful explosive and should be treated as H.E. bombs. The 6 lb. bomb is a cardboard cylinder 20 in. by 3¾ in.; the 60 lb. bomb, which may be fitted with a nose extension rod, is 42½ in. long (including the extension rod) and 8½ in. diameter, and also made in cardboard. Without the extension rod it is 34 in. long. All are painted bright green. No. 5—Pull igniter No. 6—fuzed in tail. Nos. 11 and 15—fired electrically.

Johnny Dangerously contains a scene actually involving a bomb dropped from a plane on the casino of his enemy, Roman Maronie. Followed by an explosion. Followed by a declaration of FARGIN WAR!! But I can tell you - nobody who has ever heard that whistling noise will ever forget it. I am nearly 81, and I was 8 at the time, and I can remember it all too well. I wrote about my father evacuating my mother, brother and sister and I to Larkhill, to get us away from the London blitz and the battle of britain, which was now in full spate. iv) The 500 lb. smoke bomb is of sheet-steel construction painted green. It is 13·1 in. diameter, is fitted with a tail and contains a phosphorus filling.ii) Armour-piercing steel bombs are of 500, 1,000 and 1,400 kg. These are distinguished by a dark blue stripe painted on the tail vanes and/or on the tail cone, or by the tail cone being painted dark blue all over (German marking, PC).

I got a scholarship to the Salisbury Cathedral Public School. I must have been the only pupil who could not read or sing a note of music. I won the Scholarship because the headmaster was impressed by my wish to become a designer, and because i knew exactly what I had to do to get there.

Sounds of bombs falling

Normally when the bomb goes into a dive, the propulsion unit cuts out and the light fades, but cases have been reported where the bomb has glided some minutes before impact, with the propulsion unit cut out; it then falls with a slight whistle. In other cases again, the bomb has dived with the unit still running. In some instances the bomb has turned a complete circle at the end of its flight before diving, but usually it continues on almost a straight course, turning slightly to the left—or port—as it dives. The interval between the propulsion unit cutting out and impact with the ground has varied from 2 seconds to 2 minutes, but is usually between 5 and 15 seconds. German Stuka bombers in WWII initially had had wing-mounted sirens to intimidate their targets. When this practice was stopped (the sirens added drag), they began adding whistles to the bombs themselves, creating this effect. N.B.—Magnesium bombs, when burning on wet ground, may smell like acetylene, which sometimes gives rise to mistaken reports that they are of a type containing calcium carbide.) We also witnessed many aircrashes due to training aircraft hitting each other or loosing control and hitting the the ground.
