Tim Wright, an ATA craftsman, examines a Short Takeoff/Vertical Landing (STOVL) F-35 model in the 16-foot transonic wind tunnel during a model change. The information from this testing, the final entry in a series of tests, will go into a large database to refine and validate the aircraft designs for flight testing and ultimately, production of the CTOL and STOVL F-35 variants.
