Comco
Comco is the de facto name of an American company operating two Boeing 757 aircraft.
Overview
Little is known about the exact nature of their operation, but the aircraft are believed to operate on behalf of the United States Department of Defense. They are often confused with the similarly secretive and sparsely marked Boeing C-32B Gatekeeper aircraft, modified 757s operated by the U.S. Air Force.The aircraft are painted white, and have either the word COMCO on the tail or stylized blue sweeps on the tail, fuselage, and engine cowling. The Federal Aviation Administration registry lists the owner of the aircraft as L-3 Capital, assumed to be a subsidiary of defense contractor L3Harris Technologies.
When parked and unused, the aircraft have padlocks which seal each of the exits, a highly unusual modification for an aircraft of its type and size.
