Speaking of too cold.... I'm researching accidents related to pilot incapacitation, and this gyro accident came up:

"On the downwind leg of the flight the aircraft was observed by witnesses to depart controlled flight, tumble, and impact the terrain. Witnesses stated that during an attempt to revive the pilot he had an accumulation of one quarter inch of ice over his eyes and face." (CHI91DEP03)

Yow.
