John Monnett always thought of himself as a jet pilot, but as his 50s began drawing to a close he realized the only way that was going to happen was if he built one himself. Luckily for Monnett, his day job is founder and president of Oshkosh-based Sonex Aircraft, a kit builder already known for airplanes like the Sonex-B, the Xenos-B and the OneX.
