This looks like a good deal.
For £4m they get the aircraft they need, at a better price than they expected.
They get an AOC, meaning they don't need to pay to borrow someone else's and/or acquire their own.
They get systems, management, cash-flow, suppliers, aircrew, cabin crew, etc without start-up costs.
They get a couple of 757s thrown in, with a year's contracts in place.
And since the Chairman of Silverjet is also Chairman of FJE, presumably he hasn't sold himself a pup.
Roll on Silverjet, Luton to the World...
