No pressure suit?!
Pretty amazing he ejected at 70,000 and survived without a suit, eh?
You couldn't fit through the hatch wearing a pressure suit. I read elsewhere it was a design decision. To have the multiple large viewing windows (for use of paying customers) meant there wouldn't be enough structural strength with a larger hatch. So pilots, and future customers, must do without pressure suits. Obviously transparent Aluminum technology isn't yet ready for the big time.
