One of the many problems with "warbirds" is that the aura / mystique of superpilots in superplanes leads to the operators cutting corners, and the experienced pilots themselves breaking rules that they had observed their whole professional careers. The B17 crash in CT revealed poor maintenance (by the chief pilot himself), no oversight by, or adherence to rules agreed on with the FAA, and carrying passengers at airshows in a not completely airworthy plane. Oswego B17 same thing. Thankfully no one was injured in that case. In the Dallas CAF b17 collision a whole room full of experienced pilots, who had been practicing CRM throughout their careers, sat and silently approved an obviously dangerous plan for the display, and reportedly not for the first time. Including the head of the CAF.
Fun fact: Disney owns the land where the former Glendale CA airport (the first commercial airport in California) once stood. The original terminal building has been meticulously restored. I'm sure they would denounce the Mickey Mouse 'tactics' the pilot used in this incident. [Joking is necessary to cushion the ridiculous behavior of this 'pilot' who caused a crash that was totally preventable.]
One specific comment/correction. The T-28 pilot was only required to have corrective lenses available for NEAR vision. His not wearing them would not have been contributory to not seeing the other aircraft, and you can't fault him for that particular fact. You harp on him pretty heavily for that, and it demonstrates a lack of detailed understanding on your part.
Good discussion. 29:19 If the T28's radio #1 was on 125.00, Whiteman Ground Control, I wonder if he ever switched to the tower frequency for takeoff clearance?
