When did this customs chase take place ?
By the sounds of it though, geographically it wasn't the one that me old man was wondering about, as that was in the 70s. I have found little or nothing using google, the only vague mention (undated) was of a woman who flew a helicopter into a prison (Brixton,Wandsworth,Wormwoodscrubbs ???) and 'sprung' her man, but of a stolen whirlybird, nada.... Maybe it was one of our lady whirlybirds
The flightpath took the gaggle of aircraft over Wimbledon towards the south if that helps at all

Btw, can someone fill me in on the 'customs chase' event please, sounds interesting.
