The 1013.25 mbar (101.325 kPa) pressure for altimeter settings is NOT
"arbitrary" as Kilopascal & Wiki write. The standard altimeter setting for
worldwide altimeter settings was determined from the mean surface pressure
level.

For starters, the SAE wishes people would not refer to them as SAE fasteners

Still lots of confusion out there!

Military planes collide while in formation because of mis judging inertia, I
don't think it made any difference here. Feet or meters, it's just a number on
a dial. That's what most people don't understand, it would take I flight with a
meter altimeter and altitudes in meters to get used to it. A
