iii) A flare with a casing of about the same size as (ii) but without tail fins and with "MARK 50/F/A" or "MARK C 50FA" stencilled in yellow, green or red lengthwise on the body. It would appear that the colour of the stencilled marking indicates the burning colour of the flare composition. Pink Floyd, The Wall uses the sound. Pink's father is killed by a bomb from a dive bomber. Since the plane dropping the bomb was an Axis plane during World War II, it might actually have been a Stuka.

Invoked in Alpha Protocol; in the fight with Sean Darcy, he makes this noise by whistling when he throws grenades at you. Earlier in the game, you can see mortars being used against enemy mooks; these make the correct noise.

Physical problem of whistling

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). A version of the bomb with both wings removed and the propeller blades reduced in size to a triangular shape is shown in Figure 4. In this version an impact fuze is fitted.

Invoked by accident in the M*A*S*H episode "The Kids": Cpl. Klinger is reading "The Three Little Pigs" to a little Korean girl who is one of Nurse Cratty's orphanage children taking refuge at the hospital. When he whistles as a sound effect of the wolf sliding down the pigs' chimney, the little girl starts crying and he has to console her. 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.

Sounds of bombs falling

All such balloons, both British and German, are liable to leak, in which case they may come to the ground still partially filled with hydrogen. British practice bombs are of three types, differing in weight and material, but all are of the same shape. The dimensions are—length 16–18 in. maximum diameter 3 in., tail vanes 3 in. long and all have a small lug approximately 5 in. from the nose. The most common type of flame float is the cylindrical wooden body fitted with a metal nose and tail fin assembly. It is 13 in. long overall, 3 in. diameter, and contains a flare composition.
