The extra large Shuttle suit, without anybody in it, holds 5.42 cubic feet of air; the extra small size holds 4.35 cubic feet. Then, his pressurization hose somehow became disconnected and LeBlanc became the only person to survive near-vacuum pressures when his suit dropped from 3.8 psi to 0.1 psi in 10 seconds.
