On 29 April President Ford ordered OPERATION FREQUENT WIND, the helicopter evacuation of Saigon.
Vietnamese pilots now began flying themselves and their families out of the country in anything that could get off the ground. Some headed for the American rescue fleet just off the coast, while others flew to Thailand.
In the final evacuation, over a hundred SVNAF aircraft arrived in Thailand, including twenty-six F-5s, eight A-37s. eleven A-1s, six C-130s. thirteen C-47s, five C-7s, and three AC-119s.
During the final North Vietnamese assault on Saigon, numerous South Vietnamese aircraft escaped with their pilots to Thailand. Among these were four F-5As plus 22 F-5Es. These planes were returned to the USA where they were placed in storage pending sale to other customers.
Most of the aircraft that evacuated from Tan Son Nhut and made it to Thailand were fixed wing. A few helicopters were able to reach Thai territory, though some ran out of fuel and were forced to land along the coast in Cambodia.
Most of the aircraft that flew out to the ships were helicopters. Close to 100 VNAF helicopters landed on U.S. ships off the coast, although at least half were jettisoned. Two O-1s managed to land on the USS Midway (CV-41), one of which was also jettisoned.

Immediately following Operation FREQUENT WIND, the USS Midway steamed south into the Gulf of Siam to Thailand and brought aboard over 100 American built aircraft preventing them from falling into communist hands.

When they were aboard, the ship steamed at high speed to Guam, where the planes were offloaded by crane in record time.
