MASSIVE Thread creep
I'm 6' and fit ok (just).
In the RNZAF potential A4 Pilots were given a 'rail ride' before being posted to 14 Sqn, in other words the Gunnies disconnected the seat, attached a crane to the top of it, got you to strap in and then hauled you out of the cockpit (obviously the canopy was removed). It was supervised by an AVMED Doc who had to sign off on it and would stop the crane at various points to see how close things got.
Having said that the top of my helmet and left shoulder touched the canopy and the 'HUD stoop' pretty much screwed my back for a couple of years but it was the a effen great jet to fly!
ps a 6'2 ish Kiwi who must have gusted 90KGs punched out OK...left his seat pan somewhere in the Manawhatu but he was fine.
