Having read some of the other articles on that TASS site I wouldn't believe anything they say.
here's kommersant on the same subject with a picture of a smoking hole claimed to be something that used to be a mig31. Did the crew survive? Dunno, that's what they claim.
But you have a point there: if a news agency works in Russia, it's stories are officially approved so they publish the Kremlin truth. Need for a grain of salt.
