A Belgian Air Force F-16 hit a Libyan People's Air Force Su-22UM3K plane on the ground during an operation on 27 March. On 9 April, a Free Libyan air force Mi-25D combat attack helicopter (serial number "854"—the same one that was captured by the rebel forces at Benina air force base on 23 February 2011) bombed positions of Gaddafi's soldiers at Ajadabiya, but it was then shot down by Gaddafi loyalist forces; its pilot captain Hussein al-Warfali was killed. Also on the same day on 9 April, a Free Libyan air force MiG-23BN fighter jet was intercepted by NATO fighter jets over Benghazi, and escorted back to its base in accordance with the UN-authorized and established no-fly zone over Libya.
