Please remain in your seat and use the seat belt at all times.
Avoid standing in the aisle or next to the toilets, unless absolute must.
Yeah, I'll remain in my seat for 10 hours, sure. And then I end up with a thrombosis when I get off the plane.
It is no good to sit for such a long amount of time, so why are you giving that advise?
Aircraft these days are highly maintained, the systems have multiple levels of redundancy, and they go through rigorous checks periodically--the whole jet gets almost dismantled in a "heavy maintenance" check. Anytime something is mechanically wrong with the plane, the Captain writes it up in the logbook--his professional responsibility--and the mechanic checks it, fixes it, signs the book that it is fixed --again, his responsibility--and the Captain has to sign off on that. It is a system of checks and balances. This all happens before the aircraft even leaves the gate.
Then why are there still plane crashes? Especially in these hard financial times I worry that the airlines cut corners on safety and maintenance...
