Here are some more facts:
1, We had 6 TriStar tankers, all paid for. Even a comprehensive life extension and servicability upgrade would have cost little compared to FSTA lease.
2, RAF TriStar had a virtual full house of drogue clearances. RAF TriStar did not need Hi/Low speed drogue.
3, Cash/Credit flow was easy with RAF TriStar due to the fact it was paid for and, had a low utilisation cost.
4, RAF TriStar fulfilled the role of NATO and European widebody AAR shortfall tanker for 25 years.
"Of course Air Chief Marshal, the FSTA will be shiny and new!"
