its not under water ... moves to quickly to be underwater. moronic flatard

Greetings from England. Poorly designed hatch cover. A large pizza would have been more useful or a dustbin lid. Millions of Dollars spent and no one tested how difficult it would be to close the cover? Rather like the first space walk - there were no handles on the outside skin of the spacecraft for the 'walkers' to hang on to. Result - something out of Loony Tunes. I'm not sure NASA is exactly a fountain of genius. Get a few Brits in and we'll sort it out for you.

It's not a door, it's the Quest airlock EVA hatch thermal cover.

It's NASA's underwarter testing facility you utter moron.

You are either a troll or under-educated.
