Disclaimer: I know diddly squat about aircraft
A cow-orker, sitting at my desk as I type, has, in all seriousness, suggested that the F-104 fighter jet was retired from service because “It’s so fast it shoots itself down.” It would seem this would be at least a physical improbability if not impossibility. “Yeah, it accelerates faster than the bullets accelerate.”
Now, my tenuous grasp of physics would suggest that the velocity of the bullet in flight (V[sub]Bullet[/sub]) would be equal, at least at first, to the velocity of the jet (V[sub]Jet[/sub]) plus the normal muzzle velocity of bullet at a standstill. Now, the bullet will slow down because of wind resistance, gravity, whatnot. But it should also describe a parabolic arc towards the earth.
This sounds a lot like a joke by Mad Magazine in their Star Wars issue. What’s the Straight Dope?
