Please explain how you will lift from Kabul in a Tristar with enough fuel to make the UK with any meaningful load whilst still operating to Perf A?
Very simple, Sideshow Bob, it requires a tech stop for refueling.
Done all the time with all of the UN flights, ex-ROB.
It really is an easy exercise, perhaps the RAF...don't know how?
NB. This really rather basic question leads me to believe that some folks...haven't a clue.
No surprise...
