21 Squadron SAAF was first formed on 8 May 1941 in Nakuru, Kenya, as a bomber squadron flying Maryland medium bomber aircraft. The squadron consisted of pilots from Squadrons 11, 15, and 16 of the SAAF. From November 1943 to February 1944, the 21st Squadron was based at Totorella in the province of Foggia, Italy. Baltimore, Anson, and DC3 planes were flown on bombing raids mainly over central Italy and into Yugoslavia. On 21 February 1944 the squadron moved from Tortorella to Campomarino, south east of Termoli, where bombing continued, mainly of railways and marshalling yards. 21 Squadron SAAF was disbanded on 10 September 1945.
VIP Squadron
In 1968, the squadron was reformed at AFB Swartkop flying a Vickers Viscount and three Douglas Dakotas. The squadron acquired Hawker Siddeley HS-125 in 1970 and Swearingen Merlin in 1975. In 1985 the squadron moved to AFB Waterkloof. In 1983 the Viscount was transferred to 44 Squadron and the Merlins were sold in 1985. Two Beech KingAir 200Cs were acquired, but one was later sold and the other aircraft transferred to 41 Squadron. The HS-125s were disposed of in 1999. The squadron currently flies a fleet of jet aircraft. The two Dassault Falcon 50s were acquired in 1982 and 1985, the two Cessna 550 Citation IIs in 1983 and the Dassault Falcon 900 in 1992. In January 2003 the squadron received the new presidential Boeing BBJ. The Boeing 737 BBJ is known as "Inkwazi", meaning "Fish eagle" in the Xhosa and Zulu languages. The aircraft is based on the Boeing 737-700 and has an upgraded interior. It arrived in South Africa on 21 October 2002.
In 2012 it was found that two aircraft had followed Jacob Zuma's Boeing BBJ flight into John F Kennedy International Airport. The aircraft were using SAAF callsigns. The aircraft were a Bombardier Global Express and a South African AirwaysAirbus A340. In response to the reports, then Chief of the Air Force, Lieutenant General Carlo Gagiano said that the aircraft followed to ensure that the president could make it to an important meeting after his New York visit. The Democratic Alliance said that Sisulu should take responsibility and explain why the aircraft were used.
Acquisition of new aircraft
In 2012 plans were announced to acquire a new Boeing 777 VIP aircraft for the SAAF in a R2 billion deal. The order was cancelled after the offer had lapsed. In 2015, Armscor opened the tender process for a new VIP aircraft for use by the president. Analysts speculated that an aircraft meeting Armscor's specifications could cost R4 billion.
Accidents and incidents
On 26 May 1971, during a practice flypast for the Republic Day celebrations, three HS-125s crashed into Devil's Peak. All on board were killed. The accident was attributed to low visibility due to bad weather conditions.
In 2009, the aircraft carrying Deputy President Kgalema Motlanthe made an emergency landing in the Democratic Republic of the Congo as it was running low on fuel. There were no injuries.
In 2011, the aircraft carrying Deputy President Kgalema Motlanthe made a precautionary landing in New Zealand due to a warning light activating, caused by a faulty sensor in the aircraft. Also in 2011, mechanical difficulties on an aircraft intended to be used by the Deputy President caused the planned official visits to Finland, Sweden and Denmark to be cancelled.
