Нисам нашао конкретан догађај на овим странама  које си поставио(мада научих доста о 27. и њеним наследницима  ),али овде се помиње та несрећа(врло кратко,додуше...)


The Su-37's life ended when T10M-11 (serialled 711) was lost in a crash on flying a ferry flight in Russia. The aircraft was not fitted with the TVC engines at the time of the crash. No other Su-35s have been converted to Su-37 specifications, nor has the Su-37 design entered production. The Su-37 was never an official designation recognized by the Russian Air Force. The crash of 711 effectively means the end of the Su-37, although future Su-35 developments will be more like the Su-37 of 1996 than the original Su-35. The possibility remains that the designation Su-37 will be used again in the future for other TVC-engine powered Flanker variants.
