Found an article on the internet which makes interesting reading from 1983:
"
Carl Beaman's company is in the best tradition of calculated business gambles and private enterprise. When he left the Fleet Air Arm in 1969 he couldn't face the prospect of joining all his contemporaries who were heading for the Far East and the North Sea as privately employed pilots.
With his wife Annette he saw the potential in taking over management of other people's helicopters and flying them at a profit to owner and manager alike. The first step on his way to turning CB Helicopters into a £500,000 turnover limited company was when Roger Daltry – lead singer with The Who – offered Carl his own Bell Jet-Ranger.
It was Daltry's helicopter that we were flying in as we passed Central London's only other heliport, a large floating barge near the City water-front, 1,000 feet below us.
"It suited Daltry because he wasn't able to maximise the potential of his helicopter on his own. He knows that our pilots are all highly trained ex-servicemen who would fly it safely and properly. He takes a percentage of the business we do with his machine and we, in turn, maintain it and make it available to him when he needs it. Our private customers range from members of the Royal Family to politicians and entertainers."
