Yeah but.. Most commercial pilots with gliding experience are lifetime aviators. They started on gliders, went on to power and probably aerobatics, joined the military and flew fast jets, then ended their careers captaining an airliner.
I think this is the profile of Capt. Sully. Those are the guys I want up front when I'm down the back.
The 'Mr dangerous' types are those that go from zero to the airliner flight deck as their first move. They have no idea what flying is about.
