I fear to post on this thread, however I am adding my thoughts on Al_R's question regarding opening the bay doors to dispose of fuel leaking in there.
I would say that it depends on by what means the bomb bay doors are actuated. If they are operated by hydraulics, cables, levers, etc, then I can't see any problem.
However, if they are operated by electric motors, and if the motors are located in the bay itself, and if the motors are not insulated or isolated from the air space in the bomb bay, then that could make a difference. Any electric motor sparks when it is running - between the commutator and brushes. So there could be a potential ignition source, as long as all the above condition are met.
Techies will no doubt put me straight with the facts.
