Brian Gaff presented the following explanation :
So how will they get it into a Dragon? Being a pressurised unit it would
mean bringing the pump in. I'm not sure it would actually fit through the
door, it certainly won't on a Progress, but I suppose if you could open an
unpressurised Dragon and then seal it and pressurise it, but it seems rather
dangerous to me, its big and heavy and not really what you would want
banging about inside a spacecraft at re entry.

Looks like a candidate for a test of an inflatable re entry system to me!


Dragon has an unpressurized section.
