Our Vice President of Engineering (hereafter called just the VP) at Cessna during my time there in the Golden 1950s was sort of a contrary guy. For instance, he didn’t like attending meetings with the FAA, which he rarely did, I guess because he thought the Feds were so bureaucratic to deal with.
And he tenaciously stuck by certain requirements he put forth, like having all the fuel on the twin engine Model 310 in tip tanks, to get that hazard away from the passengers in case of an accident, even though we proved by flight test that having tip tanks on the airplane compromised some of its otherwise better flying characteristics. (OK, its characteristics with the tip tanks on were still pretty fine.)
And he was absolutely sure that wind tunnel tests were a waste of time.
