Watching the E-3D jousting the VC10K centreline hose (on the CCTV) looked weird enough, but the AEW3 Nimrod looked ridiculous. It had to do a climbing approach and on the CCTV when in contact it looked like a platypus.
Probably flew like one too!
Actually, consensus was that the AEW3 flew better than the MR2 - the nose and tail additions gave better yaw characteristics and Dutch roll was significantly reduced. Just a shame that the Mission System Avionics were pants.
As for Sentry - the flight deck crews said that the problem during tanking was when you got a little high behind the tanker and you placed the rotodome into the tanker's turbulence.
