40th Helicopter Squadron

The 40th Helicopter Squadron is a missile support unit of the United States Air Force. As the 40th Aerospace Rescue and Recovery Squadron it was a helicopter rescue squadron of the USAF during the Vietnam War.

History
The squadron was activated as the 40th Aerospace Rescue and Recovery Squadron at Udorn Royal Thai Air Force Base in March 1968 with Sikorsky HH-3s which were nicknamed "Nitnoy." Later Sikorsky HH-53s arrived and these were nicknamed "BUFF."

In March 1968, Detachment 2 of the 37th Aerospace Rescue and Recovery Squadron at Udorn RTAFB operating HH-3s and HH-53Bs, was transferred to the 40th ARRS.

The 40th moved to Nakhon Phanom Royal Thai Air Force Base on 21 July 1971.

20 August 1972, the local base rescue detachments of the 3d Aerospace Rescue and Recovery Group each operating 2 HH-43s were transferred to the 40th ARRS, comprising:
 * Detachment 2 Takhli Royal Thai Air Force Base
 * Detachment 3 Ubon Royal Thai Air Force Base
 * Detachment 4 Korat Royal Thai Air Force Base
 * Detachment 5 Udorn RTAFB
 * Detachment 12 U-Tapao Royal Thai Naval Airfield
 * Detachment 14 Tan Son Nhut Air Base

30 November 1972, with the inactivation of the 37th ARRS at Danang Air Base, 5 of its HH-53s were transferred to the 40th ARRS, while its two HH-43s remained at Danang as Detachment 7 of the 40th ARRS to provide base rescue during Operation Linebacker II.

Following the Paris Peace Accords all remaining US Forces were withdrawn from South Vietnam by 27 March 1973. Detachment 7 at Danang Air Base and Detachment 14 at Tan Son Nhut Air Base were inactivated during this period. Following the withdrawal from South Vietnam the 40th's force level was 11 HH-53s and 14 HH-43s.

The USAF continued combat operations over Cambodia until 15 August 1973 and the 40th provided CSAR support during this period. Following the end of combat operations the 40th kept 2 HH-53s at Nakhon Phanom on 15-minute alert during daylight and 45-minute alert at night.

In July 1974 Detachment 10 at Takhli was disbanded, followed in August by Detachment 3 at Ubon. On 20 February 1975, Detachment 1 at Nakhon Phanom was disbanded. At this time the 40th's force level had dropped to 8 HH-53Cs and 4 HH-43Fs.

The 40th moved to Korat Royal Thai Air Force Base on 1 October 1975. On 15 October 1975 with the inactivation of the 56th ARRS its 4 HC-130Ps joined the 40th.

On 31 January 1976 the 40th ARRS was inactivated at Korat RTAFB.

Operations and losses

 * 30 May 1968, Jolly Green, an HH-3E was attempting to rescue Colonel Norman Phillips the pilot of a downed F-105, near Savannakhet, Laos. Pararescueman Sergeant Thomas A Newman descended into a hostile jungle environment to rescue the pilot. Hampered by darkness and concentrated automatic weapons fire, Newman requested the rescue helicopter to enter a nearby orbit, both for the safety of the crewmembers and to prevent the hovering aircraft from establishing their location for the unfriendly ground forces. When the HH-3 returned, he secured the injured Philips to the forest penetrator and protected him with his own body as they ascended to the helicopter. Newman was awarded the Air Force Cross.
 * 25 December 1968, Jolly Green 17, an HH-3E was attempting to rescue Major Charles R Brownlee, the pilot of Panda 01 an F-105 shot down near Ban Lathama, Mahaxia District, Khammouan Province, Laos. Pararescueman Airman First Class Charles Douglas King descended by rescue hoist to rescue the injured pilot. With the pilot attached to the hoist, the HH-3E and King were hit by enemy fire, seriously injured, King instructed the helicopter to depart. King was posthumously awarded the Air Force Cross,. The bodies of King and Brownlee were not recovered and both were listed as killed in action - body not recovered.

A pararescueman was lowered to the ground at the site of the crash to check for survivors, but due to the intense heat from the burning helicopter, he could not approach near enough to determine if there were crew members inside the aircraft. Some three hours later a second rescue specialist was deployed in the immediate area, who reported the wreckage was still burning, precluding close inspection. The 5-man crew were all killed in action - body not recovered.
 * 13 April 1972, Captain Bennie D Orrell pilot of a Jolly Green, rescued a downed pilot near Tchepone, Laos. Orrell was awarded the Air Force Cross.

Stovall pilot of a Jolly Green, flew through intense hostile ground fire to complete the rescue of Captain Roger Locher, an F-4 copilot who had evaded capture for 23 days after being shot down in North Vietnam. This rescue was the deepest CSAR mission into North Vietnam and took place 8 km northeast of Yên Bái Air Base, one of the most active Vietnamese People's Air Force MiG airfields. Stovall was awarded a Bronze Oak leaf cluster in lieu of a second award of Silver Star. Stovall was also awarded the 1973 Jabara Award for Airmanship.

Aikman, who had a broken leg, knee, elbow and jaw, McGrath exposed himself to intense ground fire in order to drag the incapacitated Aikman to a suitable recovery area. Seeing JG73 crippled by the hostile fire, he directed air strikes against surrounding hostile ground forces until he was able to secure CAikman and himself to the penetrator of Jolly Green 57, the backup helicopter.
