But despite the maturity of the basic F4U design, the risks involved in flight-testing design changes remained. On 8 July 1946 test pilot Dick Burroughs was killed while attempting to land at the Tweed New Haven Airport following an engine failure in the XF4U-5. Later that year, project pilot Bill Horan survived a risky bail out of an F4U-5 following an engine failure during a high altitude dive test over Long Island Sound.
