Hercules C-130E-LM 10322

Ferry Flight 1991-October-30 to 1991-October-30

435 Transport and Rescue Squadron (Certe Provehendi) CFB Edmonton. Hercules C-130E-LM aircraft 10322 struck high ground and crashed on approach to Canadian Forces Station Alert, Ellesmere Island NWT during the semi-annual "Operation Boxtop" supply airlift to the station. At 508 miles from the geographic North Pole, CFS Alert is the furthest north permanent human settlement on our planet

Boxtop 22 was the 22nd flight of the second airlift of 1991. Crewed by Aircraft Commander Capt JP Couch, First Officer Lt J Bales, Lt M Moore, Navigator; Sgt Paul West, Flight Engineer and MCpl Roland Pitre, Loadmaster/Traffic Technician

There were thirteen passengers aboard the aircraft, a mix of military and civilian personnel flying in for duty or to attend to various services for the staff at Alert

For the first time on one of these flights, the Hercules was also carrying an internal bulk fuel tank containing 3,400 litres of diesel fuel for use at CFS Alert. When the aircraft crashed, it broke into three pieces, causing the internal fuel tank to burst open and catch fire

The remote location and weather made any rescue response extremely difficult and hazardous but a massive rescue operation was undertaken involving 24 Canadian and US military aircraft as well as 2 Canadian civilian aircraft

Hundreds of dedicated air and ground search and rescue personnel, persevering despite the most extreme weather conditions and rugged landscape were involved in the recovery

The rescue involved aircraft and personnel from Canadian Military: 103 RU, Gander, 405 Squadron, Greenwood, 408 Squadron, Edmonton, 412 Squadron, Ottawa, 413 Squadron, Greenwood, 415 Squadron, Greenwood, 424 Squadron, Trenton, 429 Squadron, Trenton, 435 Squadron, Edmonton, 436 Squadron, Trenton, 440 Squadron, Edmonton, 442 Squadron, Comox. Canadian Civilian: Greenland Charter Air Services and Bradley Air Services US Military: 11th Air Force, Elemendorf, 22nd Air Force, Travis AFB, 56th Air Rescue, Kleflavik, Iceland

MCpl R Pitre CD (CAF), Captain JA Trepanier CD (CAF), MWO T Jardine CD SSM (CAF) and WO R Grimsley CD (CAF) were killed in this accident

Capt JP Couch (CAF) survived initially and helped other survivors after the crash but died of hypothermia before rescuers arrived

There were thirteen survivors among those aboard: Civilian R Thomson, Civilian S Hillier, Lt J Bales (CAF), Sgt P West (CAF), Lt M Moore (CAF), Capt R Dumoulin (CAF), Capt W de Groot (CAF), MWO M Tremblay (CAF), MCpl T Cobden (CAF), MCpl D Meace (CAF), MCpl M Ellefsen (CAF), MS D Montgomery (CAF) and Pvt B Vance (CAF)

The CC-130H Hercules is primarily used for search and rescue operations. While it also carries out transport missions, its main focus is saving lives through the Canadian Armed Forces' search and rescue mandate. It has a range of more than 7,200 kilometres and can transport approximately 80 passengers, operate on short unpaved runways and fly in severe weather conditions. These capabilities make the CC-130H an excellent aircraft for search and rescue operations over the vast span of Canada's central and northern regions. RCAF Web Page

435 Squadron History Summary 1944-46

History of the Squadron Post-WWII (Aircraft: Dakota, Boxcar, Hercules)

No. 164 (Transport) Squadron was created on 23 January 1943 at Moncton, New Brunswick . The squadron flew Lodestar and Dakota aircraft on East Coast transport duty. It was the RCAF’s premier transport squadron and the cornerstone of the peacetime Air Transport Command. It provided trained aircrew as the nuclei of other transport units. On 1 August 1946 it was divided into two units, one at Dartmouth, Nova Scotia and one at Edmonton, Alberta . The Dartmouth squadron become No. 426 (T) Squadron and the Edmonton detachment was re-designated 435 (Transport) Squadron. It flew Douglas Dakota IV aircraft until 1952, then re-equipped with the Fairchild C-119G Flying Boxcar. The squadron relocated a few miles north to RCAF Station Namao in 1955. From 1960, it flew Lockheed Hercules C-130B, and from 1966 the Hercules C-130-E. Due to the Chrétien government's budget cuts and the resultant closure of the airfield at CFB Edmonton, the squadron was moved to 17 Wing Winnipeg in 1994. It was re-designated '435 Transport and Rescue Squadron' on 1 May 1995. The squadron is now based at 19 Wing, Comox, British Columbia . 435 Squadron is the only Air Force squadron equipped and trained to conduct air-to-air refuelling of fighter aircraft in support of operational and training activities at home and abroad. The CC-130 Hercules tanker is a key asset for the Canadian NORAD Region in its mission to defend Canada and the United States against aerial threats that originate outside or within North American airspace. The Squadron has been operating the tankers in support of fighter operations since 1992.
