Well I thought it was funny........
Seeing the PATCO thread reminded me of a story told to me by one of the ex-PATCO guys in Abu Dhabi way back when (and if it's not true, it should be!)
Aurora Centre : Speedbird 123, turn left thirty degrees for noise abatement.
Speedbird 23 : Aurora, confirm this is for noise abatement? We are at FL390!
Aurora Centre : Speedbird 123, have you heard the noise two Jumbos make when they hit each
other?
