I haven't been able to locate a thread devoted to this subject so I would like to start one by posting this video obtained with an infrared camera by Win Keech, a crop circle researcher in the UK. Here is his introduction to the video, followed by the video.
"Third time lucky! Seems F-Burks don't want me posting this! These are BOLs that I filmed marking out the Southfield Swallow formation in 2008, a couple of days before it appeared. I was stood at the bottom of Knapp Hill filming this, chatting to Geaof Ward. Neither of us could see this by eye - only the IR cams could. Obviously ignore the cars crossing the Alton Barnes road and the odd chopper/plane flying past. This is digitally zoomed and the gamma reduced for easier viewing - link is here, Win. x"

{is there a device by which I can directly embed videos here?}
