Classic British Flight Sim

Today while flying over the Middle East in the Super VC10 I was at FL350, just over 300 KIAS with a 160 knot tail wind, GPS recorded a ground speed of 660 knots at one point

It's great when you get a helping hand like that isn't it. I always looked forward to picking up the jetstream coming back to the UK From the US
