Gama's always been independant of Bond - different companies, different owners, was established in 1984 and is now the UK's largest operator of Business Jet Aircraft and has been a contract holder to the Scottish Ambulance Service since 1997.
Gama supported Bond's move into Fixed Wing back in the early 90's (as Gama had been operating King Airs for 10 years by that point, and they helped write the Bond Fixed Wing AOC Manual).
This new contract is for the provision of two brand new Beech King Air 200C's and two EC135T2's. Gama isn't a specialist helicopter operator, so has subcontracted that work to Bond, but they're not a linked company other than working together on things in the past.
