How do Photographers Remotely Capture the Space Shuttle?

With the historic last launch of the space shuttle Endeavor, I got to wondering how the photographers remotely trigger their cameras to photograph the launch.  Since the public has to be 3 miles away from the launch site, it would be WAY too far for a Pocketwizard. Fortunately, BorrowLenses.com posted a link on their facebook page that answered my question.  Just thought I’d share the video with the rest of you.  It’s quite interesting.
