gotta admit I like that also!
At the Silbury seminar EH said they have bought two aerial laser scans over the last few years and are looking to buy another in the future. (I wonder how much That costs?)
Now laser scanning from a plane is a hobby I could happily take up! Especialy as one of my friends has just purchased a 2 seater Chinese Fighter plane (please let it still have the guns attatched) ;)
