On this topic, here is an interesting one to ponder. I am working at a busy European airport. Anyway during my training in regard to air safety I was told by an airport official that a pilot travelling in the jump seat had a claw hammer in his carry on luggage. Once at altitude he struck the captain across the head. The first officer then over powered him and made an emergency landing.
Apparently the pilot in the jump seat wasn't screened correctly for whatever reason, I don't know.
So just a thought, you might have good intentions of flying safely from A to B, the guy helping you fly may not.
Its the world we live in guys and I suppose every little is worth doing when it come to air safety.
I think you're referring to FedEx accident.
