Just an observation based upon a couple of posts here.
I've been nearly killed once by a recently retired commercial pilot:15,000 hrs and it turned out had forgotten most of the airmanship he had presumably once known about operating single engine piston aeroplanes.
Holding a commercial licence and having been flying for a lot of years (as, being 70, this chap presumably had) does not necessarily indicate that somebody knows how to safely operate a small aeroplane with a whirly thing on the front.
