Back to the topic. There was a proposal from a contractor about 5 years ago to replace the RAF Jetstream multi-engine trainer a/c at Cranwell with J31's to be operated on the civil register by Eastern Airways. Serco won the contract instead and they purchased King Airs. Nevertheless, couldn't there be a "call off" contract with someone like Eastern to provide a similar service. Pay for a given number of hours, with additional flights above that being charged at a pre-agreed additional rate.
