the CTs, conducting bombing missions against their jungle bases. Although results were often difficult to assess, they allowed the government to harass CT forces, attack their base camps when identified and keep them on the move. Later, in 1958, Canberra bombers from No. 2 Squadron RAAF were deployed to Malaya and took part in bombing missions against the CTs. During the Vietnam War, from 1964 to 1972, the RAAF contributed Caribou STOL transport aircraft as part of the RAAF Transport Flight Vietnam, later redesignated No. 35 Squadron RAAF, UH-1 Iroquois helicopters from No. 9 Squadron RAAF, and English Electric Canberra bombers from No. 2 Squadron RAAF. The Canberras flew 11,963 bombing sorties, and two aircraft were lost. One went missing during a bombing raid. The wreckage of the aircraft was recovered in April 2009, and the remains of the crew were found in late July 2009. The other was shot down by a surface-to-air missile, although both crew were rescued. They dropped 76,389 bombs and were credited with 786 enemy personnel confirmed killed and a further 3,390 estimated killed, 8,637 structures, 15,568 bunkers, 1,267 sampans and 74 bridges destroyed. RAAF transport aircraft also supported anti-communist ground forces. The UH-1 helicopters were used in many roles including medical evacuation and close air support. RAAF casualties in Vietnam included six killed in action, eight non-battle fatalities, 30 wounded in action and 30 injured. A small number of RAAF pilots also served in United States Air Force units, flying F-4 Phantom fighter-bombers or serving as forward air controllers. In September 1975, a group of 44 civilians, including armed supporters of the Timorese Democratic Union (UDT), commandeered an RAAF Caribou, A4-140, on the ground at Baucau Airport in the then Portuguese Timor, which was in the middle of a civil war. The Caribou had landed at Baucau on a humanitarian mission for the International Committee of the Red Cross. The civilians demanded that the RAAF crew members fly them to Darwin Airport (also RAAF Base Darwin) in Australia, which they did. After the Caribou arrived there, the Australian government detained the civilians for a short period, and then granted refugee visas to all of them. The Guardian later described A4-140 as "the only RAAF plane ever hijacked", and the incident as "one of the more remarkable stories in Australia's military and immigration history".
