The Pereira X-28 was a single-seat flying boat designed by Eut Tileston under contract to George Pereira, a private builder. It was also known both as the Air Skimmer which was Eut's designation and as Osprey I (Georges designation). The US Navy commissioned the plane through the Naval Air Development Center as part of a study for patrol missions in Southeast Asia. The study required that the aircraft be capable of flight under visual flight rules (VFR), lightweight, cost fewer than 5,000 American dollars in quantity and be able to be manufactured in Southeast Asia. The aircraft was first flown on August 12, 1970
The only known surviving aircraft is now on display in the Kalamazoo Aviation History Museum.
