How about this then. Going on a 3 hr nax ex (in my days at the delightful CCAT) stuck in a bathtub in which I couldn't move (the Katana 2 seat job). Was the tour of around birmingham (across to Gloucester, then up to some where near Liverpool and back down the uncontrolled corridor to Cranfield). Only problem was, got stuck depserately needing a pi55 overhead Wrexham! Right in the middle and no way directly back.
It took 9 fills of the fuel strainer and a steady hand trying not to let the venturi blow it back in my face when emptying it overboard! People could still see the off-white stain down the side of that a/c for months - think it was deicing fluid, honest!
