This picture was distributed in a recent Apco email newsletter. They don't mind it being shared around since it's good publicity for Apco! Of the handful of photos provided, this one was a stand-out for me. Plus its portrait orientation makes it look bigger on my website page!
The wing is an Apco Thrust HP, flying over a dam in the Peak District of the U.K. The photographer was Paul Haxby, of the AXB Sports company. The jpeg image file tells me he was using a Canon EOS 350D (Digital) camera, for those interested in such things. The Thrust is a CEN Standard rated wing apparently.
