I flew a 737 with a bloke who once told me it is ok to fly 15kts greater than VMO if the air is clear, because Boeing design the plane with a huge tolerance, I am sure he would win this discussion!
@westausatc 360 KIAS on a 767 and the leading edges would start to glow! Did he work for QF or Air Bro?
ps. Are you from Perth? Good knowing a fellow Sandgroper is keeping us safe in DXB
