Gallery: David Vetter's Spacesuit return to index
David and his mother inspect the suit. David learns that he must carefully crawl through a tunnel from his isolator to the suit each time he wears it to keep outside air from getting inside the suit.
"Have the subject crawl through the tunnel to the suit either head first or feet first... If the subject crawled through head first have him turn around within the tunnel."-- User's Manual, "Suit Donning"
