Oregon-based investment firm High Plateau Ventures has acquired Business Air, one of two FBOs at Denton Enterprise Airport in Denton, Texas, along with its charter division, which operates five aircraft ranging from a King Air B200 to a Learjet 45. The FBO, occupying more than 20 acres at the Dallas/Fort Worth-area airport, has an 8,000-sq-ft terminal with 150,000 sq ft of hangar space. The FBO’s new owners expect the latter number to grow with the construction of a new 24,000-sq-ft hangar capable of housing the latest ultra-long-range business jets.
