High Altitude

Scan-371

Another part of my dad’s Army Air Corps training involved a couple of other things we don’t encounter in a normal commercial air flight these days.  One was the required use of an oxygen mask and a calculation of the percentage of oxygen needed.

The other lesson was in “Boyle’s Law” and how the change in pressure of a descending aircraft could affect the crew.
