what happens...

[helper]

what happens when you fire a bullet when you are flieng at mach two
(a bullet usualy flies at mach 1.5 i think)
does the bullet go back or is it boosted by the speed of the plane

[The UberThor]

Assuming a bullet flies at mach 1.5 normally, it would go mach 3.5. The speeds more or less add. This goes for all matter (but not light)

[seffy]

Agreed. A bullet will travel at Mach 1.5(?) from the weapon it is fired from. If that weapon is travelling at mach2, then the two speeds are added. However, due to the increased friction at such speeds, I doubt it would be as accurate as normal or, if you ignore the mach2 aspect, that it would have it's usual range.

about the accuracy is true. fighter jets fire bullets from 'gatling cannon' type weapons, the shots from them are all over the place (within reason, they seem to deviate anyway, probably about 1:100 ratio)

[William_Muddy]

There is some deviation with all conventional weapons. With bullet speeds being fired from jet air craft, the pilots tend to lead their bullets into targets in arc-firing formats to off set the deviation. Also the barrel on alot of modern aircraft is angular; that is to say that bullets are not actually being fired directly in front of the firing air craft but are slightly below (generally) to the fight path of the aircraft even during level flight.
