If you are using film, use high speed film so you can eliminate the blurs. For the digital, point and shoot. The biggest problems we have encountered is the need to get far enough away for video. Still shots are not a problem and one can use close up lenses. I wish the video cameras would come with "far away" lenses. The zoom in, they just don't zoom out (wide angle).
The problems with video are, therefore, setting up far enough up wind and still being able to get a clear shot (with no people in front). I am sure Windy will be there doing a full video of the proceedings. Matt will bring his video carera and undoubtedly shoot some flights. His is digital. The big question is, can one get in the proper position for taking the shots up wind. I don't think they are going to want a lot of spectators running around the area, and if the wind is in the wrong direction, well...?
