Wait a minute here...I've got an idea....not too long ago I read a couple articles about the US Air Force doing experiments with fixed wing rotorcraft hybrids....kind like on The Sixth Day but without the cool transformer aspect. Anyway, supposedly, the jet engine for the regular fixed wing mode doubles as a motor for the rotor by diverting the stream from the back into two separate exits at the tip of both rotors, facing opposite directions to get the rotation effect. Now, if they can supposedly lock a rotor into a fixed position with enough resistance that it can be used as a fixed wing...couldn't they can design a locking rotor that has a saftey mechanism that makes it lock in place in the event of mechanical failure, making it possible for the cockpit to have a normal ejection seat?
If that's too mechanically difficult, I'll one-up Paq's idea. Forward diagonally ejecting seats, eliminates some of the speed of the descent, while assuring that the chopper doesn't fall on top of you.
