- Looks like a C172 to me (but I might be wrong). Are you, according to the POH, allowed to perform negative-g manoeuvres with pax and baggage in the back? Isn't this restricted to the utility category, or plainly forbidden altogether?
Can't quite see the horizon well enough to tell, but doesn't that look like nothing but a rather "spirited" stall demonstration? Even so, nothing in the POH that prohibits negative-g maneuvers in the normal category...
Stupid, but not forbidden...
