Silent Film of Pressure Suit Test!

Here is some silent video of a pressure suit test, I am in a Bell Jet Ranger helicopter going to just shy of 20,000 feet, but the suit is giving me pressure--through the 45-minute flight--that fooled my body to think that it was at just 11,000 feet! The suit held pressure, dumped my exhaled C02, maintained a good temperature, and gave me enough mobility to work the controls! All A-OK!
