Oxygen is our main concern. Remember, the glider altitude record is a
little over 50,000 MSL.


Are oxygen and heat sufficient to keep a pilot alive and
cognitively competent at that altitude or is a pressure
suit needed?


A complete run down of last year's altitude record flight can be found on
the following web page.

The simple answer is yes a pressure suit is need. The previous record of
over 49,000 MSL was set without the aid of a pressure suit. Even with a
good pressure breathing oxygen system the pilot suffered significant brain
damage due to the oxygen deprivation.
