The '''Osprey GP2 Osprey''', also known as the '''Air Skimmer''', '''Sea Skimmer''', or '''Pereira GP2 Osprey''', was a single-seat [[flying boat]] designed by Eut Tileston under contract to [[George Pereira (aircraft designer)|George Pereira]], a private builder. After the release of Pereira's amphibious [[Osprey Osprey 2|Osprey II]] some years later, this aircraft became known retrospectively as the '''Osprey I'''. The original plane was designed to be water launched only. Initial test flights were performed in the Sacramento Delta.<ref name="Osprey I Flying Boat">{{cite magazine|magazine=Sport Aviation|date=Nov 1970|title=Osprey I Flying Boat}}</ref> A single example was evaluated by the [[United States Navy]] as the '''X-28'''. Pereira formed Osprey Aircraft to market the plans to [[Homebuilt aircraft|homebuilders]], including plans for a trailer that allows the pilot to launch and recover the aircraft single-handed.<ref name="JAWA 85">''Jane's All the World's Aircraft 1985–86'', p. 606</ref> These plans are still marketed by Osprey Aircraft {{as of|2014|October|lc=y}}.<ref name="Osprey">Osprey Aircraft website</ref>

The Navy became interested in the project through a [[Naval Air Development Center]] study into patrol missions in Southeast Asia.<ref name="Osprey" /> The study required that the aircraft be capable of flight under [[visual flight rules]] (VFR), be lightweight, cost less than 5,000 US dollars, and be able to be manufactured in Southeast Asia.<ref name="X-Vehicles">Jenkins, Landis and Miller 2003, p. 36</ref> After examining Pereira's Osprey in 1971, the Navy purchased the aircraft and commenced testing is as the X-28A in the fall of that year.<ref name="Pima">Pima Air & Space Museum website</ref> Although the Osprey met most of the requirements of the program,<ref name="Pima" /> the program itself was cancelled without any further military examples produced.<ref name="Osprey" /> The sole X-28 is now on display in the Kalamazoo Aviation History Museum.<ref name="Osprey" />
