Maybe my handle gives it away, but there is only one candidate - and I still have the wrists to prove it. The Shack was the last truly manual aircraft in service - and flying it at low level on ASW ops (or even in the circuit) required a fair bit of manual labour and equally strong leg muscles. Incidentally I have had the pleasure to fly the Meatbox, Hunter, Hastings and the Chinook (double Hyds failure in the sim only thank god - and all you can do IS say your prayers), but I would be happy to be corrected by the Sunderland fraternity.
