The TSR-2

The BAC TSR-2 was to be the RAF's foremost combat aircraft for the 1960's onwards, replacing the Canberra in the Tactical Strike/Reconnaissance role. The aircraft was to have supersonic capability at tree-top height and was the first aircraft in the World to be equipped with a Head-Up-Display (HUD). The TSR project was subsequently murdered in 1964 by a short-sighted Labour government, and all project material and prototypes ordered destroyed. A decision motivated mostly by pressure from the US to not compete with their F-111 Aardvark in the global market.
