Why did the hover-chairs deploy oxygen masks when the captain activated the Holo-Detector and the passengers went to the Lido Deck?

    A good question. The script seems to indicate that it's an automated safety procedure but it doesn't say why it was there

    My personal guess is it's because real life astronauts wear their helmets during take off and landing.

    @sag Real life astronauts don't technically need them either from what I understand. It's an additional level of safety in case life support fails, as takeoff and landing are the most precarious parts of the trip.

    google.com/amp/s/www.seeker.com/amphtml/… Apollo 7 is an example, where the procedure said for the astronauts to wear their helmets during re-entry, but the astronauts refused, and they landed helmet-less.

    This post was locked for content dispute once. I don't think it's a good idea to start that all over again.

When the ship performs a hyperjump, the passengers are thrown clear off their feet and experience a considerable amount of stress including multiple head impacts.

enter image description here

The script describes the hoods as the space equivalent of "life preservers", basically a wise precaution against any sort of incident that might occur during hyperflight when seated in a mobile chair. Note that there's no good indication that these masks contain an oxygen breathing apparatus. If anything they seem to be more geared toward protection from head injuries given that they're labelled

"Emergency Safety Helmet"

on the side of the hood and don't fit flush to the face or neck.

Per the script


...Floodlights kick on everywhere...
...The LIDO DECK POOLS automatically cover up...
...Stray PASSENGERS pause to take in the alarms...
...SPACE-LIFE PRESERVERS burst from their hover chairs...
...Inflate around their necks...
...GREEN LINES appear on the floors...
...SLEEPING PASSENGERS are involuntarily led out of their cabins...
...Every hover chair follows the illuminated lines...
