There is a big difference between tooling around in Hunters and Harriers. If you don't understand that, I suggest you stop posting here - you are wasting your time.
There is also a big difference between
a few Hunters (for example) in private hands
and actually having the capability to deploy a worthwhile force to CVS/F for any period of time. Have you forgotten how little deck time JFH got between 04-09? The fish-heads said we were so out of currency that we were "dangerous." I believe you may have agreed at the time.....
And that was a professional force of 3 Sqns of full-time Harrier pilots, maintainers and support staff.....
Your idea will never work. The Harrier is gone from UK service. It will not come back. Fact.
