Walking on Butser Hill near Petersfield, Hants this morning I heard a once familar sound and then a Gazelle AH.1(?) appear from behind the crest. Heading I guesstimate 170°ish (wondered if it was heading for Baker Barracks/Thorney Island). To be honest I had forgotten they were still in service - 50th anniversary of the first UK order for 60 was this August.
