From inside the book:
Boeing Military Airplane Company's model 464 series, known more commonly under the formal military designation B-52, stands tall as the unquestioned high-water mark of U.S. strategic deterrent forces in the post-WWII period. Tagged with the official name of Stratofortress, crewmembers more generally refer to it as the "BUFF", meaning "Big Ugly Fat Fellow".
