At 600 USG/min that's got to be the best part of an hour in contact to get 100 tonnes. You'd want a UARSSI surely?
Right, which must make probe refuelling an E-3D for say half a fuel load must be great fun. How long does this take?
So, yes, UARSSI pls (oh look, like E-3Ds). And a KC-45A would be great with all the bells and whistles (and RR Trents.)
