More thread drift I'm afraid ........ I'm not a heli pilot (although I do fly fixed wing and gliders) - but my father-in-law was.
He claims to have been one of the first pilots to introduce the Jetranger into the UK, and spent some time perfoming demo's of this type all around the UK as it gained popularity. I'll check through his logbooks with him when we next meet to see if he had any connection with G-TALY. He went on to fly as a company pilot for a chap named David Brown (in Huddersfield I think) as well as doing a lot of instructing. He retired from chopper flying about 10 years ago now.
