Huh?
LMAO
find out who depressurized all that air--he's your culprit!!!
"...allowing depressurized air into the cabin..."
Yup! That depressurized air is ubiquitous stuff! Works its way into PRESSURIZED cabins at high altitude every time!
Too bad divers don't know about this - depressurized air down there deep could allow for fast ascents without fear of the bends...
Any pressurized plane can experience a loss of cabin pressure. That is why airliners have the little drop-down oxygen masks for passengers. USAF Lear 35/C-21s have a good safety record, and I maintain that they are fine aircraft.
