I would say that this technically possible. Limiting factors would be the structural strength of the aircraft (in this case the amount of negative G that the airframe can take) and the ability of the fuel system to keep the engines running when inverted. No doubt the gyros would have all tumbled. When I was responsible for the research simulator at BAC Weybridge I would sometimes try such stunts with aircraft such as the VC10. It was very difficult to do the whole of any looping manoeuvre whilst keeping within the flight envelope. (safe speed and G loading) The sheer power-to-weight ratio of such aircraft when empty is amazing. I remember being a passenger on a test flight with Brian Trubshaw in command doing circuits and bumps in a VC10 at RAE Bedford as part of the autoland program. There were only a couple of jump seats in the passenger cabin and I was standing at the cockpit door watching the plane land itself. It was necessary to hang on very tightly each time that the throttles went forward for the next go-around.
