Absolutely correct. And that sub has a total complement of 55-60.
Now take a look at the escape pod, count the rungs in the ladder welded on the outside. (I get 10, but a trained photo interpreter may do better.) I estimate 16" spacing which would make the whole thing roughly 15' high. Measure the total height vs diameter at the thick part and I get roughly 11' in diameter. That is 95 sq. ft. Imagine an upper and a lower set of seats, and we get 190 sg. ft. for 60 people. Or about 3 sq. ft. per seat.
It is certainly possible to get 60 men in that space. It is not going to comfortable, but it is not that far below economy class airline seating. Keep in mind that submariners are selected for small stature and it looks very reasonable. Bets the heck out of drowning on the ocean floor.
Not what I see. Look at the two guys in the open hatch wearing some kind of protective gear. Could you put 60 of them in there? I doubt it.
I'm not sure that's an escape pod at all. Why the protective gear? Could it be the nuclear fuel? Notice there is no one else around. Normally there would be guys all over the place when lowering a load like that into a small space.
Or, it could be the warp core and the guys are protected against anti-matter leaks.....
