The position that airline crew should refrain from suing for negligence on the basis of the fact they fly the aircraft is total arrant nonsense. If an aircraft crashed due to negligence and the crew were killed, would you deny the family of the crew the right to sue? So what is the difference?
If your car bursts into flames due to a manufacturing fault, are you telling me that the mere fact you were operating the car at the time means you should refrain from legal action?
Airline crews make claims all the time, for many different reasons including hearing loss, fumes exposure, violence encountered from passengers and harassment; all of them inherent risks in the environment we operate in that the airlines and manufacturers are required by law to mitigate.
If a fumes exposure ended your career, or caused a deformity to your children, would you refrain from taking action on the basis that you were flying the aircraft?
To single this crew out is ignorant.
That said, I really feel the content of this thread is now pushing the boundary; and if people don't know the facts, they really should refrain from silly uninformed comment.
