Well without an impartial T&E set up (Boscombe) you would have to take the manufacturers word for it all, or hope the US test and operate their assets in exactly the way we do ! For example shall we leave the AAR trials for the A400M to Airbus. MMMM A400M reciever (Airbus) oh and FSTA tanker (Airbus). I am sure they would be open and honest about that ! Having been in the T&E business for many years I can tell you that the manufacturer will tell you exactly what you want to hear and on more than one occasion when looking for a safety case the Americans hadnt actually done any of the trials
