A museum piece aircraft, the Mach 3,XB-70 Valkyrie, is suddenly moved from the exhibit floor of the Air Force Museum at Wright-Patterson AFB to Hangar 18 where a "Skunk Works" team of scientists and engineers rebuild it to fly again on a high priority mission halfway round the world...The government and Air Force have an aggressive combat mission in mind...but the crew who will fly Valkyrie have another.
