Hercules stationed at Halim Perdanakusuma airbase at Jakarta. Despite the warning from United States to not use the aircraft for the operation, it soon scrambled over the Papua for the airlift mission, due to the loss of C-47s, to Dutch Hawker Hunters and P2V Neptunes. The C-130's high altitude flying capability made it less vulnerable to interception. 6 Douglas DC-3s and one Convair 240, under Wing Garuda 011. The aircraft were modified from civilian use for airlift operations. 6 anti-submarine Fairey Gannet AS.4s, several PBY-5 Catalinas and two Grumman HU-16 Albatross (UF-1 variant). These aircraft belonged to the Indonesian Naval Aviation, but supporting the air forces for the Operation. Aircraft were stationed in Liang airbase at Seram, then moved to Morotai airbase. One Gannet AS.4 was lost due to an accident when it crashed into a mountain in Seram island, killing three crew members. Several Bell 47s, Mil Mi-4 and Mil Mi-6 helicopters were planned to be used for the operation, but were not ready during the early phase of infiltration of the operation. Indonesian MiG pilots received training to fly their fighter aircraft in Egypt before the infiltration campaign. During the infiltration of the airlift campaign, the air forces' special forces, (PGT) (now known as Kopasgat) landed in Klamono-Sorong, Papua. Also during this period, the Indonesian Air Force also took part in the confrontation against Malaysia (which was backed by the United Kingdom) along the border of Kalimantan, the Malacca Strait and near the Singapore maritime border, wherein Air Force aircraft faced their counterparts in the Royal Air Force and the young Royal Malaysian Air Force. 30 September movement and the overthrow of Sukarno (1966–1970) The coup attempt led by the 30 September Movement in 1965 changed everything and a new anti-communist regime from the Army, led by Major General Suharto, took power. The Chief of Staff of the Air Force, Air Marshall Omar Dani was removed from his position and court-martialed for his purported involvement in the coup. Ties with the Eastern bloc countries were cut, and thus support and spare parts for the planes became short. By August 1968 the situation was critical, and in early 1970, the Chief of Staff of the Air Force, Suwoto Sukandar, said that the spare parts situation meant that only 15–20 percent of aircraft were airworthy. The MiG force made its farewell flight with a flypast of Jakarta in 1970. The
