[@TheMadAsshatter] The important part for JR was that he set off a plasma grenade in the airlock, fusing the front of his suit and blowing him out into space. Currently he's floating outside the ship with a limited air supply.

The others have pretty much just stood around in the corridor just the other side of the airlock so far, so JR doesn't need to worry about anything he's missed out on.

Just a tip: The main hangar doors are jammed open a couple of meters, so JR could easily get inside the ship that way if he wanted to.
