While the TF-X is likely over a decade away from computer-aided design sketches to production, the Transition is expected to take to the air at this week's EAA AirVenture Oshkosh in Oshkosh, Wisc., in front of a crowd of an estimated 50,000 spectators, according to Dietrich's own estimation. Given Terrafugia's capacity to assemble nearly 100 Transitions per year once production begins, in a burgeoning market for cars that can also fly, he hopes that the Transition's run will make a formidable impression.
