Russian MIG's Chase a UFO- Caught on Video

These MIGS were scrambled to intercept a slim cylinder Unidentified Flying Object (UFO) but when the Russian jets catch up with the UFO it takes of at incredible speeds. This video was classified but has recently been released and Now since then the debunkers are saying this is a standard target practice exercise. But then why was it classified for so long?
