I am a Staff Sergeant in the United States Air Force. I am currently stationed at Offutt AFB, Bellevue Nebraska. Here at Offutt I fly onboard the Air Force E4-B (http://en.wikipedia.org/wiki/Boeing_E-4). Onboard the aircraft I am a Airborne SHF Operator. The aircraft is a militarized Boeing 747 that is equipped with state-of-the-art communications equipment. The aircraft's mission is to serve as a survivable mobile command post for the National Command Authority, including the President of the United States, the Secretary of Defense, and successors.
