Well, the solution seems like it should be simple. Right now, you
create a single bullet object and associate it with the plane, then
you center the bullet on the plane when you press spacebar. What you
should do instead is create a new bullet object every time the
spacebar is pressed (or, alternatively, create a new one every so
often while the spacebar is held down). I'd suggest you keep a
separate sprite group for all bullets, and put it in a place where all
your classes can access it (at the module level seems like a good
idea).

Oh, and do keep in mind that if you do pygame.image.load() every time
you make a new bullet, you will have the same image in memory multiple
times, which is quite wasteful. Instead, you should load it once and
reuse the same image for all your Bullets.

HTH,
