Haha, I remember Billy Connolly one time talking about these safety issues...
"Can you imagine you've got your life jacket on and are heading upside down for the atlantic ocean, thinking 'I'm alright'".
He went on about how it is a load of bollocks that they try to make us feel safe with oxygen masks and lifejackets etc...
"Cause they're lying to us, ya know. If they were to tell us the truth they'd have to say 'ladies and gentlemen, in the highly unlikely event of loss of power to all four engines, in all probability we'll go into the ground like a f***ing dart'"
"You won't be screaming - you'll be trying to get the seat in front of you out of your mouth"
"We'd be obliged if you would put on your safety jacket. This will do you no good at all; but when archaelogists find you... in 200 years... they'll think there was a river here"
