For me - 8.00 in a GR1, 27 Aug '91, Marham to Dhahran leading the return to the Middle East post-GW1 for Op Southern Watch. We didn't get any dispensation to over-run the engines. I'm amazed those F3 engines made it all the way.
I am aware of an RAF pilot who has done over 23 hours at the controls of a B2 (obviously with AR) and I also believe the record was in excess of 40 hours.
