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.) The whistles were purposefully attached to the bombs. Their purpose was to weaken enemy morale and to enhance the intimidation of dive-bombing. Look at the Stuka dive-bomber, a similar case. What other purpose did it's sirens have? As far as warning the target, it's too late to get to safety once you hear the whistle if you're not there already (bombs fall fast). Not all bombs were equipped with whistles, but they still all made noise as they fell due to air displacement (just not the famous whistling sound). As a boy who wanted to be an aircraft designer when he grew up, I was fascinated to watch all the latest aircraft flying in and out of Boscombe Down test base. (I later achieved my ambition). My favourite reading was a series of books called "Aircraft of the fighting Powers"

Izzie - Someone on the ground would actually hear the pitch increase. In other words, it sounds higher and higher as it approaches. So that means those beloved filmmakers are using the wrong sound…

Sounds of bombs falling

When found, some or all of the candles are likely to be burnt down to a short stump, and will be attached to the housing of the igniter unit, an aluminium pressing resembling a saucepan 5 in. deep (see Figure 57). Incendiary bombs with the explosive charge in the nose plug irrespective of whether the nose plug is electron or steel are known as type B; viz., B 1 EZ–B and B 1.3 EZ–B. These were at first marked by a red painted B on the flat of the nose; a later marking is ZB or B stamped on the nose. (See also the markings given on the I.B.E.N. and I.B.S.E.N. in Figures 12 and 13.) Wing span—17 ft. 6 in. with little or no taper in the wings, or in another version (as shown in the silhouette)—16 ft.

There is usually little difficulty in distinguishing between a parachute mine and a bomb since the former has no tail vanes and its rear end is likely to be found open. There is, however, obviously more likelihood of confusion with the parachute bomb, and the distinguishing features to be borne in mind are the latter's oval shape and its characteristic parachute, which is of a different shape, size and colour from that used for mines (see Section I ( a) (vi) and Figures 9A and 9B).

World War II MMOFPS WWII Online includes sounds for falling bombs. If you're close enough to hear it, you're probably dead. The in-game Stukas are equipped with a toggle for the Stuka whistle.

The normal American smoke bomb is the 100 lb. bomb. It is identical in external appearance with the American 100 lb. incendiary bomb except that a yellow band surrounds the body and the filling contains phosphorus. The 5·5 in. flare is similar in appearance to the 4·5 in. flare but weighs 41 lb. and is 48 in. long by 5·5 in. in diameter. 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. The German balloon measures about 4 ft. long when deflated and weighs from 1 to 2 lb. The Germans have also used balloons of French manufacture, similar in construction to the British type. The distinguishing features mentioned above may, therefore, not always be present. There is also a special German fighter, called Stuka, designed to make a whistling sound every time it hits. This has the same effect as falling bombs (the aircraft can emit this sound just before the bomb falls, so it is very important to distinguish it). Physical problem of whistlinglb. Practice Bomb. This is of plastic construction and is therefore likely to be very badly damaged when recovered. This bomb is smoke-filled only, and the marking is the same as on the 11½ lb. type. 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. Any of the devices described below may be attached to barrage balloons and, when these break loose and are found on the ground, care should be taken not to touch either the flying cable or the devices attached to it. The police should be informed immediately. The change in the pitch of sound was due to the Doppler effect. When the bomb is dropped from the airplane, the velocity of the bomb goes on increasing due to gravity until it reaches its terminal velocity. As the bomb approaches towards the ground, the pitch increases and thus the “kooouuuueeee” sound. Does it make sense but? 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!!

The Germans are now using a large number of different containers to carry small incendiary and anti-personnel bombs, and flares. Most recent types are marked "AB" or "ABB" and are meant to open at approximately predetermined heights below the aircraft, according to fuze setting. The initials AB stand for " Abwurf" = a throwing out, " Behälter = a container, which taken together indicate the later types which are released intact from the aircraft; the additional B stands for " Brandbomben" = incendiary bomb, though other than incendiary bombs may now be carried in containers marked ABB. The BdC 10, BSK 36, Mark 500 Boden, Mark 250 BK and Mark 250 LK are. also released from the aircraft.

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. A larger oil bomb weighing about 250 kg. of the same approximate dimensions as a 500 kg. H.E. bomb has also been dropped. (Note: The Germans call these oil bombs Flammenbomben, i.e. flame bombs, the latest types being known as Flam C 250 C and Flam C 500).
