B-2 Spirit Stealth Bomber Poster If this has always been one of your favorite aircraft then this is the poster for you! It appears that this B-2 has exceeded the sound barrier close to an open ocean by the looks of that ring around its tail, but it has not. In reality the B-2 does not exceed the speed of sound and the apparent cloud effect is caused by the Prandtl-Glauert Singularity. Size: 16" X 20" comes laminated, printed with archival ink on enhanced matte paper. Photo credit: U.S. Air Force photo (AFFTC) Bobbie Garcia
