http://www.cnn.com/2014/09/19/us/russian-plane-incidents/index.html The fact the two bears and refuelers were escorted with antiquated cold war museum pieces, i.e. MiG-31's, tells me this was just Ivan being silly. The MiG-31 was designed to launch from it's base and climb to high altitude rapidly to intercept our old super sonic B-1's. It is not that well suited to the fighter escort role. Would have been a duck shoot for the Raptors and the Russians knew it. Whole incident seems to only have entertainment value vs any strategic significance.
