uh... I dont know about that... Alrightey lets think this our for a second.... a 50 cal BMG has a FPS of only 2900, with 665 grains, and a projectile diameter of .510 inches. Now say this round carries a 12" diameter "cone of destruction"
Now say a.... Ah F-14 does a super sonic low fly by (As they do at airshows) with a weight 72,900 pounds going 1,584 mph (Mach 1.88 a bit slower than a .50 cal projectile) BUT with a size of 38 feet wingspan with wings swept back this would mean that the so called "Cone of DEATH" on this aircraft would be about 912 feet in diameter.

The shock wave seen in this picture is water in the air condenceing with the blast wave is about 50 feet in total diameter, True it could be deadly, But only if you were around 10 feet from the aircraft at the time be in this wave because of rupture of your interals organs, But that would MAINLY be from the sound wave of the sonic boom and displacement of the air and vibrations. many pictures taken are from at or alot less than 1,000 feet from the aircraft. Now with the mass of this aircraft being 218,700 times larger that this projectile weighing 218,700 times smaller could not possably be a chance that a .50 cal projectile at .5-12 inches away would tare a limb from a body or be near enough for the shock wave to rupture any internal organs, not even your ear drum's.
Therefore your misinformed about this...
Oh and trust me... the bullet can in no way cauterize a wound with its heat, the heat would not even make the tissue inflamed at that speed.
