Gosh, where to start.
My benchmark was the jolly old Victor, we always knew we would get an excellent service; notwithstanding that a wing hose at the top of the height bracket in "Q" fit (F4) was interesting; having to tickle a burner made the transfer rate almost negative.
The best transfer rates were, Vulcan, Victor centre, Albert and KC10 centre.
The most flexible were the Vulcans and Alberts ( particularly in FI - lovely LL tanking!)
The most obstructive was the VC10, they seemed to have combined the most restrictive of AAR and truck rules,not to mention the bloody dihedral!
The KC 135 was just hilarious!
There are two sorts of pilot, those who've spoked ? and those who are going to.
