As somebody who did air-to-air refuelling from the receiving end before converting to liners (also did certification tests behind new pods for export ..) please consider that apart from flying the big heavy boat with pods and so, to really now if the aircraft is suitable you have to be fly in many configurations for hours with different types of fighters in the back. You have to monitor turbulences especially, otherwise apart from putting the fighters upside down which is the limit, first you will have a very touchy business to master for the fighter pilot (and it's not on autopilot..)
Now which one will fly best "through" the air, the 330 or the 767 ?
Anyway, that's unquestionably a big contract
From the back, the best one was the VC10 - the worst the KC10 !
