True, although fortunately the air supply is meant to last for 4 days. As a passenger I would probably be more alarmed about the apparent absence of some kind of distress beacon than the inability to open the hatch without help.

Well, something went wrong and one of the things that could go wrong is the air supply. I wouldn't be a passenger for any amount of money, these are experimental tools, not joy rides.

There was a distress beacon… it’s called a transponder. It is in a separate pressure chamber controlled by a separate battery. It is a completely separate and isolated system. It failed at the same time as regular comms leading some to conclude the vessel was gone. Kaput. Is no more.
