Behel was a certified fighter jet pilot who also enjoyed flying high-performance single-engine race planes.
[8] In 2010, Behel purchased "Sweet Dreams", a custom built, one of a kind[9] experimental GP-5 aircraft powered by a Chevrolet small-block engine.
[1] In April 2014, Behel set three class world records in Sweet Dreams at the Experimental Fly-In at the Mojave Air and Space Port in Mojave, California: Speed over a 3 kilometres (1.9 mi) course, 3 km time-to-climb, and speed over a 15 kilometres (9.3 mi) course.
[4][12] On 8 September 2014, Behel perished while flying Sweet Dreams during a qualifying heat at the Reno Air Races.
Around the 5th outer pylon, in an area of the course known as "High-G Ridge",[6] sections of the right wing broke away from the airplane, which then rolled sharply to the right and impacted the ground.
The crash occurred during a qualifying heat early in the 2014 Reno Air Race program and was investigated by the NTSB as well as the FAA.
