safetypee, that's most interesting.
I recall when we first started refuelling Nimrods in the 1980s, there was a procedure we had to go through to check proper fuel transfer. "Fuel flows, fuel stops, fuel flows..." during the first stages of any onload to the Nirmod. A legacy of the somewhat rudimentary Malvinas war probe system and associated plumbing?
The check was later dropped once the systems had been improved, I understood?
My AAR role check included a Nimrod AEW3. Having watched it jousting away trying to catch the drogue as its front radome bow wave pushed it away, I always wondered how much fatigue the probe system was designed to take....
