How do I get off this sub? [W]

Hint 1 of 7:

You first need to get the rest of the ship's crew out of the way.

Hint 2 of 7:

Create a distraction as described in the "How do I get to the forward
torpedo launch?" question.

Hint 3 of 7:

There are only two exits from the sub, and the one on top is guarded.

Hint 4 of 7:

The other exit is through the forward (torpedo) launch.

Hint 5 of 7:

Since you're alone, you cannot get someone else to pull the launch lever.
