Sub 1000 ejectee from a Mk 4 seat at low level - a little shorter for the experience! Enjoyed the 1000 dinner at the Dorchester in about 1966? Spent about 11 hours strapped in - Marham to Travis with a big refuel over Goose - copilot decided that he wanted a pee but having stood up and made the necessary dress arrangements, couldnt do it after all and waited until we landed, 5 hours later! Always had a piss on the grass at the last minute and never used the p-tube ever!
