* 12 December 1995: Two Su-27s and an Su-27UB of the [[Russian Knights]] flight demonstration team crashed into terrain outside of [[Cam Ranh]], Vietnam, killing four team pilots. Six Su-27s and an [[Ilyushin Il-76]] support aircraft were returning from [[Langkawi International Maritime and Aerospace Exhibition]]. The aircraft were flying in echelons right and left of the Il-76 on their way to Cam Ranh for refueling. During the landing approach, the Il-76 passed too close to the terrain and the three right-echelon Su-27s crashed. The other aircraft landed safely at Cam Ranh. The cause was controlled flight into terrain; contributing factors were pilot error, mountainous terrain and poor weather.<ref>{{cite web |url=http://airbase.ru/crashes/1995/12/kamran/ |last=Sidorov |first=Pavel |title=Катастрофа "Русских Витязей" |trans-title=Catastrophe of "Russian Knights" |language=ru |website=Airbase.ru |access-date=2007-04-24 |archive-url=https://web.archive.org/web/20070927032647/http://airbase.ru/crashes/1995/12/kamran/ |archive-date=27 September 2007 |url-status=live}}</ref>
