BEagle. I'm with you. The Iron Lady was (still is) a bitch. It works, but it's never pretty. Even once you're in (so to speak) there's so much that can go wrong.
Your point about the fuel flowing much faster than a UK tanker is spot on. We used to have to ask them to turn off one of the fuel pumps to prevent the 135 from rupturing the F3 fuel tanks; air couldn't get out fast enough.
The F4 could take it, though.
