Not being a fan of negative g anything, (the Stearman I used to practice
in had a nasty habit of dumping raw gas in your face from the top wing
vent at negative g), perhaps the zero g push over felt like -2 to me.
All I can say is that it was a wild ride and it should convince any of
the fast glass crowd that climbing out at best angle or best rate of
climb can put you in a position where a zero g pushover is necessary to
maintain flying speed if you loose the engine.
