The aerobatic team of the Russian Knights reported the death of two of its pilots - Colonel Oleg Irofeev and Lieutenant Colonel Vladimir Kuchetov. Both died on October 21. "The profession of a military pilot involves high risks and requires daily courage. Every flight, whether it is to carry out a mission of national importance or flights to train and improve flying skills, remains a responsible and dangerous mission. Unfortunately, losses also happen. Losses followed by deafening ringing silence. And with it comes a pain that cannot be drowned by anything," said the aerobatic team. The circumstances of the servants' deaths are not disclosed.
