And some hard drives can have problems at high altitudes because of the thin
air and their dependence on air bearings for controlling the height of the
heads over the drive platters.

Solid state drives do not have this problem.

Your cameras will operate just fine in the cold, but batteries will drain
faster, and cables will be more stiff. Plan to have lots of power, and think
about cable routing as they will hang and twist in new ways a you slew
around the sky.

A good tip I to get gloves with a mitten covering the fingers if possible.
When you need to type or handle small things, fold the mitt back so you can
use your fingers. When you're done, flip the mitts over your fingers to keep
them toasty warm again.
