Wow, I didn’t realize the other crew had timed out by a minute. In this case, thank you, FAA regs!
One of the pilots wrote a book called Hijacked.
I heard him on the radio describing the event.
The tapes of the communication to ATC are gripping.
It took about a half hour to get back to Memphis. The left seat pilot had been hit in the head with a claw hammer. He could barely see much less fly. The other pilot wrestled trying to subdue the perp. Pilot in command jerked the plane all over the sky to keep the perp from gaining advantage.
Highly recommended read.
