They did have a rather nifty
Terrain Following Radar that allowed them to do the scary low-level stuff.
It was in the little black nipple on the nose. Coupled of course with a rather nifty (if memory serves - it's a long time now) FM radar altimeter. It had 2 radar altimeters, the FM one for the accurate low-level measuring and a convention pulse radar on for the high level stuff were single digits didn't really matter.
What I can't remember though is whether the TFR actually flew the plane or just gave the pilot instructions. (may still have my course notes somewhere in the loft.)
Biting the hand that feeds IT
