A helicopter’s-eye view of the Elevated Fixed Platform (EFP), a test platform constructed on a disused taxiway at Naval Air Station Patuxent River for testing recirculation effects on the V-22 Osprey. Upon completion of those tests, two U.S. Naval Test Pilot School instructors seized the opportunity before the EFP was dismantled to conduct a flight test program that they hope will lead to a better understanding of how helicopters behave when landing on and taking off from ships at sea, rooftop platforms, and other complex environments.
