The Wedell-Williams Model 45 was a racing aircraft built in the United States in 1933.
Design and development
The Model 45 was a development of designer James Wedell's earlier Model 44 and was a low-wing cantilever monoplane with tailwheel undercarriage, the main units of which were retractable.[2]
Operational history
The Model 45 flew for the first time on June 28, 1933[2] and showed promising performance achieving an average speed of 264.703 mph on a 100 km closed course.
Wedell-Williams pilot, John Worthen flew the 45 to a second place in the 1934 Bendix Trophy race and if not for a navigation error would have demolished the 44's first place time by at least 50 minutes.[2][3]
On June 24, 1934, Jimmy Wedell died in an accident while piloting a Gypsy Moth on a flying lesson.[2] Development of the 45 was delayed following the loss of its creator. Even so, the 45 was entered in the 1934 Thompson Trophy Race. In a preliminary event, the Shell Speed Dash Unlimited, Worthen placed first with an average speed of 302.13 mph.[2][4] He then qualified the 45 with a speed of 292.14 mph, third behind the 44 and Turner's racer in the main event.[2] However the 45 was still suffering from development problems and was withdrawn due to instability.
During the Thompson race Doug Davis crashed the 44 and was killed instantly.[2] Devastated, the Wedell-Williams team dismantled and trucked the 45 to Patterson. It never flew again.[2]
In rapid succession, the remaining Wedell-Williams principals were killed in air crashes: Walter Wedell, Jimmy's brother, was killed in a crash on July 18, 1935.[2] Company co-founder Harry Palmerston Williams and chief test pilot, John Worthen were both killed on May 19, 1936 in a crash.[2]
After the death of Williams, the Model 45 was donated to Louisiana State University, where it eventually disappeared, its final fate unknown.[2]
A full-scale replica Model 45, constructed by Jim B. Clevenger of Kissimmee, Florida, is on display at the Louisiana State Museum in Patterson, Louisiana.[2]
