No probs Heli-Ice...a pleasure.
JS75......I am suprised you are being fobbed off in this way so directly unless your specific request for photography is to do with advertising a commercial product.....your last reply suggests it is.
That said, there are many precedents where this has hapend before, but it invariably means that you had to edit out the RAF branded bits on the ac...you will find quite a few companies do it this way.
That all said, I still think it is worth you following previous advice and contacting the RAF SARF Chief of Staff at Valley. I am sure he will give you a hearing and if he feels you have a case, will advise you accordingly.
Cheers
