As yet I have not been able to get a straight answer from any of the staff at EGSY. The impression I get is that we ourselves know more than they do. I looked at the apron and could not see the single engine aircraft that were on the Sheffield Aviation site.
I will have to get the other half to use the same interrogation techniques on them as she does me when I come home p1ssed up with kebab down my front.
Thanks to those with the b'day wishes and merry xmas all!
