THIS is the moment Ukrainian forces managed to take out a Soviet-era Russian amphibious aircraft for the first time. Ukraine's military intelligence service HUR claims it struck two Russian Be-12 Chayka anti-submarine planes in occupied Crimea on September 21. A video released by the intelligence agency purports to show the moment the Be-12 Chayka was hit. As well as the two anti-submarine planes, a Russian Mi-8 was also taken out in the daring attacks. The Be-12 Chayka is a Soviet-era anti-submarine planes that remains in use by the Russian military.
