Sorta "hijacking" this topic: I found in some cases it is not possible to set up to drop bombs or fire rockets, no dogfight mode engaged, safety trigger up, pylons elected, jettison in off position, pipper in manual (and it jumps according to movement, what should not be). Resetted every thing and started the procedure again- no way. Even the same in AA missiles after having done a ground attack. The AIM locks, pipper reads in range, but cannot launch (and no over G in pipper). It's digusting if it happens in a long term mission....
