I can't remember the speeds and heights, but when I was there when Chiv re-opened with the Hawk, we'd recover either via Baggy Point ('Baggy Rejoin') or via the Tavistock line rail bridge over the A377 in the River Taw valley ('Barnacle Rejoin').
We were always strict to observe noise abatement rules for the benefit of the locals - unlike the fun we had on the Hunter at Brawdy!
I'd left before they built the new Officers Mess, but even with the mud and crud of all the building works - and the joy of those cold huts - Chiv truly was 'Heaven in Devon'! I just couldn't believe it when the RAF handed it over to other people - such an utter travesty.
