Flight of the Old Dog is the story of a secret highly modified B-52 bomber flying into the Soviet Union on an impromptu strike mission.

Although Moscow insists that the system does not violate existing strategic accords such as the ABM Treaty, their frequent use of the laser in striking vital US assets challenges Washington's patience before the UN.

Meanwhile, Gen. Bradley Elliott, commander of the High Technology Aerospace Weapons Center (HAWC; also known as Dreamland), tests a unique B-52 bomber with the help of several young crewmembers.

The technology tested in the plane is later adapted and fitted into two B-1 bombers that are sent to attack the Soviet laser after it destroys an American space defense satellite.

After faking a crash outside Seattle and forcing a KC-10 crew in Shemya to refuel them, the Old Dog enters Soviet airspace and engages PVO fighters before and after destroying the laser.
