Did a few 10 trips but the one that stands out in my mind was returning from Belize. I had flown out there via Lyneham and Gander in a Herc; it took three days as I remember... The 10 was sheer luxury in comparison returning via Bermuda.
Not only that but four of us had a very tight connection with a trooper from Luton to Gut. Brize bless their socks stuck us on a 10 and flew the four of us to Luton.
