Gama have always had the Scottish Air Ambulance contract for fixed and rotary wing, and up to 31st May 2020 they subcontract the rotary wing element to Babcock. From 1st June 2020 Gama will operate the whole contract themselves, and have three new Airbus H145s on order - two for the two bases and a third as a backup.
I don't believe the Bond family have any influence over Gama. Marwan Khalek owns >20% of the shares, as do Hutchison Whampoa if you check the latest Gama accounts. Stephen and Peter Bond have a company "Airline Investments Ltd" which owned Flybmi, which in turn ceased operations and went into administration this past February.
