BBMF is still Service manned to my understanding, and treated as any other RAF Sqaudron, all be it flying rather special aircraft.
RNHF has come more under the wing of the FAA due to Airworthiness regs but is very definately not an RN squadron.
The team do a superb job given that they work with unique aircraft with unique supply and support issues and limited funding as a Charity organisation.
What point are you trying to make pr00ne?? If you've got a stack of spares for historic aircraft, or a bespoke workshop, then I'm sure the RNHF would love to hear from you.
