For the record, I'm not a member of the Strato-Shitters club. Thank you,... thank you very much.Your flight suit is sealed up tighter than a drum with no integrated neck seal? PHEW! So that particular David Clark suit must have been "Huggy's Forever".
The neck seal was a mod the Shuttle crews did to the suit. We actually do have a face seal, so that the face area gets 100% O2, and the rest of the suit is ambient. You "don't smell shit" until you open up the visor in the chocks. By then, the cockpit is ripe.


Luckily, the Trader didn't have a long rollout! Much jubilation that evening at the Peninsula Hotel, calming shattered nerves. Hallalujah for HK's beautiful relatively new, modern, mucho safer airport!
