It is a powered canopy with a mechanical actuator, so you just open/close it with an internal cockpit switch, or you can also open it with a switch near the boarding ladder inside an easy access panel on the exterior of the aircraft from the ground. My point was just that the canopy was likely already in the full up position. It's pretty easy to get in and out of, especially single seat aircraft like this one, or the front seat of the family model. You have to duck down a little to get in and out of the back, but there aren't brakes back there
To your point though, the hard part of getting down is that it is a long jump down from the LEX, and especially so onto a steel hangar bay deck. It would be hard to not break something, even if you weren't doing it under duress with a moving aircraft.
I do find the 737 flight deck a pain in the ass to get in and out of. Don't know how many times ive hit my head on that stupid overhead panel, and half the seats are a struggle to slide aft/over. I would actually argue it is more difficult to get in and out of than a fighter aircraft. Though there aren't nearly as many things you have to connect up to once seated of course
