I would say the standard Russian practice is denial. In the case of the conversation we had with the Russian ambassador here, there was a whole bunch of other theories: They were jammed, it was electronic warfare, and they were not Russia's. As Russia tends to do, it put out a smokescreen of other possibilities. They haven't denied that the MiG-31s flew in the direction that they did. They certainly say that it wasn't into anybody's airspace. Again, it's the usual pattern of Russian denial.
