AirClues
If the aircraft is N reg then either the FAA or an FAA DAR will issue a ferry permit. This is not an ICAO Annex 6 certification
On the back of the the Ferry Permit ( a pink post card size document) there are some limitations.
One of which is the the Permit is valid for flight over US airspace ONLY !
Flight over any other countries aircraft must be validated by that country !
So the UK CAA will actually approve the flight out of UK
