Merlin negative G cutout too quick?

You didn't watch the video. It's not a roll, it's an inverted flypast.

I did watch the video. It is a cut scene from a movie that has nothing to do with reality.


I just checked the Mk I Operating Notes. Flying inverted is normal provided the engine is set up not to foul the aircraft with glycol and oil. It is done at high speed with the throttle closed and the pilot is instructed not to reopen the throttle until oil pressure is restored.
