Looking for A-14 (or similar) pressure breathing diluter demand regulator
Thx for the clarification. Proof that second hand information often gets corrupted in the re-telling! Guilty of passing on the "mask coming off scenario" that was not verified. Is there a written account somewhere of this flight? Also curious with how he dealt with his exhalation moisture. Heard he vented his mask to the outside of the AC. Maintaining visibility can be a lot of work at these fridgid temperatures.
