They should have known that the "wings fall off" switch is in the passenger compartment in the Cessna Cherokee PA-747, as seen in thus briefing card.
Well done the pilot for breifing his pax so they could operate this switch even when unconcious
Just a thought though, would our insurance premiums go down if the insurance companies realised that all those hours of labour charged to remove wings for an aircraft recovery actually takes only a few seconds?
I think we should be told.
