It was subsequently assessed as 72 ft a.g.l.......
Which wasn't as low as a video I once saw featuring an F4 and a
very close encounter with a Malvinas mountain radar site!
Then there was 'Blockoff' practice at Akrotiri. You were allowed to make an approach on the southern taxiway....as long as you didn't touch the wheels, you could go reasonably low. Like about 1 ft if you were careful.....then went past waving at the folks in the ATC tower. Probably banned nowadays though
