Thanks for your comments chaps, apparently they only allow four visits a year so feel very priviledged to having been accepted after applying and especially more so that the weather turned out as good as it was.
Kevin, thanks for the info on shutter speed, will have a look and see how I can alter it.
Merlin101, regarding your question of who that person was I assume you mean the Sergeant, if so...............sorry, already forgotten

The other one is Steve Bird, Head of Services of our department.
One interesting point raised during the visit to the safety equipment section and although I am bound to the Official Secrets Act in my work, I think I can mention this as he quite happily told every-one else there.
Should a pilot eject over hostile territory the locals may be tempted to hand over the pilot to their government in return for a small reward so, to try to secure his safe return back here, the pilots carry £20,000 pounds worth of gold with them as many people of these countries such as Iraq, are very poor and to make sure that they do not just take the gold and then hand him over to the government of that country afterwards, there is another reward of the same amount should the pilot be safely returned to his side.
I used to be an optimist but with age I am now a grumpy old pessimist.
