Two pilots of the Iranian Air Force were killed when, for an unknown reason, they activated the ejection seats of their F-5 fighter while it was on the ground before takeoff. Iranian radio station IRIB reported that the accident occurred at Dezful air force base in Khuzestan province. The report said that the two pilots were killed when the ejection seats were "wrongly activated."
The F-5, an aging supersonic fighter that was originally manufactured at the end of the 1950s by the Northrup company, is still used by a number of countries for instruction and training. In an accident in 2018, an Iranian pilot was killed and his copilot ejected safely. Iran acquired F-5s from the U.S. before the 1979 Islamic revolution.
Last month, there was an accident involving an F-5 of the Swiss Air Force in which the plane crashed in the canton of Obwalden. The pilot ejected and landed safely.
