Indeed, I remember standing on Measles Point on Mt Kent for the F3s to do their thing, camera phone poised, whilst the Siggie handed out score cards!
1st pass on video (must post it online sometime, although I only managed to get the part where the aircraft had already passed within 20ft of the radome and was already passing overhead and away into the distance!)
2nd pass was with a score card held above for the aircrew to "collect" their score for the previous run!
Perfectly legal & fun!
EDIT - now posted online
