Having lost ££ when Skyline went bust at Booker, I've followed the brief history since with interest. I think the problem is that they all think too big, too soon. Those 2 big hangars give people big ideas - but the facts are that you need very deep pockets to survive at the top level of heli aviation in the UK.
For training, it's just that bit too far from London - hence the Heli Air success at Denham. But for sure, Denham is now too small to contain Heli Air and the airfield owners are getting too greedy. They should be v careful - they are not the only toy shop in town.
If Denham were to cease being a helicopter training facility, then Booker would no doubt fill the gap. (And Denham is not the most rotary-friendly airfield around - no training Sat pm, no more than 3 in the circuit, and a fixed-wing brotherhood that seems to think that it's their airfield. It's a place which moans about the sound of an R22, but is quite happy to allow a biz jet to operate out of a confined runway.)
Heli Air have something like 70 orders for machines to process & certify so far this year - and Booker would let them have the space to perform this record-breaking task.
Any other heli company in Europe (or elsewhere) got an order book that big ?
