Did anybody see the programme on the History Channel about the SR53 ? It was a dual propulsion (rocket & turbine) jet that was destined to become the Nato interceptor. Got shelved because NATO & Germany were somehow convinced (Lockheed paid millions in bribes) that the inferior Starfighter would do a better job. See the link at the bottom.
