Not such a hard question (as I'm sure you know)... Lets not talk about guns though and rather, a projectile.

Where you to... project the projectiles their projected velocity would be what they normaly would be (ignoring airpressure at the... appature of the projecting tube...) relitive to the ground, the rearward projectile projectile would be stationary on leaving the projecting tube and the forward projected projectile would have twice the velocity it would normaly have. The best bit, however, is that even though they are traveling at massivly differant velocities, they'll both hit the ground at the same time! (ignoring drag, which might be might be missing the point when it comes to aircraft.)

Well, I think I can remember Physics... how did I do, Teach?
