Who wants to be a gunner or navigator in a B17 during a 3+ hour flight?

In IL-2 gunners can jump in and out at will, mid-flight.  Just find a bomber nearing a target area with an open gun slot, and in you jump. 

And in the multiplayer arena, this has led to almost every pilot 'locking' their gunner stations so people cannot join them, because 
1. The AI can many times be more accurate and thus save the pilot on a more reliable basis
2. The players that quickly jump in, will immediately start firing around, giving the position away, and generally not calling out, or not being on voice comms, making them almost more detrimental than helpful.
