In 2009, a Qatar Airways 330 had an incident in DXB while doing the pushback. The airline downloaded the CVR and found the Flight Crew NOT guilty of, and cleared them of any responsibility regarding the incident.
BUT
The pilots had been mocking AAB, and they were fired on the spot for that.
How am I sure that my family is not going to end up watching rhe snuff movie of my own death? That's my main concern, given how most airlines around the world operate.
P.S. I haven't read the full thread, I admit it.
