"...classified"

Above the only known image of Alt-B-52 serial number 61-0041. This as it appeared over Elmendorf AFB Alaska on June, 3rd 2014. The aircraft seen as it came through a dimensional rift from an alternate timeline. One where WW3 had ignited. 

The actual 61-0041 was still on the ground at it's base in Wyoming as this happened. The alternate B-52 did not respond to hails. It was tracked to it's target in nearby Siberia where it dropped it's bombs. 

Fortunately before detonation the plane, and bombs re-entered the rift returning to their original history, and we assume a war still in progress.
