Carrier Aviators flew around the boat with their canopy open. They didn't do it to look cool or cool off. They did it because it was the first step in the ditching procedure.
Same-O, Same-O at the field in the Teenie-Weenie and in the T-28 ... and basically for the same reason(s). Opening the canopy was also the first step on a PPEL .... think Four Silo Farm, if it's still there.
And we did it to look ... "cool" ... like the WW2 guys ....
