Talk:Scenario: Zero Oxygen Space Suit

Gjeremy, in answer to your question, the Mark II seal is the successor to the Mark I (Tupperware) seal, which was found to pop open rather too easily. The manufacturers were able to escape with a relatively small fine, claiming that an accidental opening and loss of Oxygen pressure would be avoided if the instructions in the operating manual had been followed correctly.
