Every branch of the MIL requires a BS to fly except the ARMY, you can get into a heli basically with a AS, non commissioned, warrant officer.....so no education required basically to wiggle a stick in a heli.
But to grasp 3D concepts such as the earth is not flat, maybe we should screen out the utterly moronic so as they don't find their way into the cockpits of Heavies creating problems for MX due to low IQ and inability to comprehend complex notions....
