I was stationed at Henlow in 1975 when XR220, the aircraft now at Cosford, was wheeled out of storage and taken to bits for transport. I managed to get a few pics, which I'm sure I still have somewhere.
The terrain following radar for TSR2 was first flown in a Dakota (TS423) by Ferranti in Edinburgh. The same aircraft featured in the TV series 'Airline' in the 80's and is now in the States. The radar never made it into TSR2 but flew regularly in a Buccaneer operated by Ferranti from Turnhouse. Despite being analogue it was very reliable and gave pilots great confidence in terrain following down to 200 feet.
