If Bombardment is somehow cast while another spell is on the stack, that spell becomes a Missile. Since that spell has no target chosen for its spell ability, it won't resolve. This is true even if that spell had a target for an ability it had.

If a card you own is a Missile and changes zones other than by being cast as a Missile, it stops being a Missile.

If any portion of your library is randomized, those cards become new objects that aren't Missiles.
