After undocking the LM Gosling says** "It just won't stay"**. Can anyone elaborate on what he's referring to? I get that it's something in the ship that's not operating correctly, but just wanted more detail if anyone has it. Thanks.

I haven't seen the movie so in what context he is using it is unknown (to me) but here is part of the Wiki article about the mission (read the 3 different sections & you might find out what he was referring to?
