Droptanks comment on the helicopter hold reminded me of the GCA into Culdrose when, feeling a bit bored after a 4 hour dunkex ( and probably overconfident with a shiny new Master Green) we gradully slowed down and reversed track back up the glideslope. Took chummy in the GCA cab about 1.5 track miles to work it out, but the patter kept us straight
Never heard another word after landing, probably too embarrased!
