Satellite images show Ukraine used drones to destroy a Sukhoi Su-27 Russian Knights aerobatic jet (NATO reporting name Flanker) on the ground last Sunday. The Russian Knights are the aerobatic demonstration team of the Russian Air Force (something similar to the famous British Red Arrows). Russia puts a good deal of emphasis on its military parades, especially the May 9 Victory parades. The Russian Knights (or /Russkie Vityazi) is one of the most common sights during these important events.
