Hi
I doubt I will be anywhere near LGW soon but if you wish, I am sure I can persuade the landlord of my local to dream up a suitable exchange scheme. Not sure it's gonna be needed. First, watch out, round about this nook of the web anyone who mentions sims of any sort is a standing Elk in front of an M16. Secondly, I have no knowledge whatsoever of those loathesome programs but I do have a friend, so close is he I cannot shut out his voice as he describes his mis-spent time at the joystick - he informs me a good joystick is an essential minimum for this exploit.
Much though I hate to indulge him I WILL pass on any requests you have and may let him near the keyboard occasionally.
He says he has no experience of anything other than FSX, Lock On and IL-2. I pass on his best wishes. He also suggests that X-Plane may be suitable or a couple of very complicated (steep learning curve compwise) freebies out there such as Flight.org.
No matter where your feet may be, keep your head in the skies.
