Recall the hangar they occupied at Biggin and saw both ARIA and AWVK on many occasions.
Decca's helicopter pilot was a chap called Edward 'Robin' Hood who was known for smoking his pipe while flying (reminds me of John Barnicle of Irish Helicopters although he smoked cigarettes!).
Teddy's main role with Decca was development of the Doppler and Navigator systems. The helicopter was widely used, not just in the UK but also on the European continent, to demonstrate both devices.
Having been imported from the US c. 1966, it went on to serve Decca for a good decade or more before being sold off to a customer in France.
AWVK was similarly used in the development of the Navigator system but also carried out a fair amount of work moving Decca's personnel.
