"But when the Su-25M1 was shot down by the Russia Air Force 6969th AB's MiG-29 on Jul. 16, the situation and condition became more critical than previous days and more Su-27 sorties were conducted to confront Russian MiG-29s. I believe those two Su-27s were not in sky just for standard practice in that day [Jul. 17], I believe they were involved in HAVCAP (High Asset Value Combat Air Patrol) mission sortie in that day."
In other words: Since the Russian interceptors had downed a Su-25 on the previous days, the Ukrainian escorted all military and civil flights over eastern Ukraine on Jul. 17. Including MH17.
Я даже не знаю, с чего начать комментирование это х-йни (простите мой французский).
Русские сбили Су-25??! Оууукэээй. Лана. И в это воздушное пространство, где "летают русские истребители" укро диспетчеры направили MH17?!!!
Хорошая новость, - они уже не могут игнорировать, что MH17 сопровождали укро пЕлоты
