Most likely to support JFACTSU given that their subsidiary, Blue Air Training, have been awarded a single source contract to deliver JTAC training by Air Commercial without competition. Most of it will be undertaken in the US on Razorback Range which is part of Fort Chaffee MTC. Don't be surprised if a pair of Alpha Jets are stationed permanently at Leeming in the future given they have DACAS, pod integration, and have the ability to provide hot drop.
As for regulatory concerns, I'd trust Transport Canada oversight a lot more than the UK CAA!
