I've never before enjoyed so many free helicopter flights. :-) I really appreciated the commentaries about flight speed and altitude etc. I don't understand about air speed and ground speed though, and why they're different. Sometime in a blog post, could you point out what the different instruments are that we could see in the video? Thanks for these videos.</p><p><a href="http://www.viddler.com/explore/Miraz/" ><img src="http://www.viddler.com/store/bigbg_51f95185.png" border="0" /></a></p> Thu, 26 Jun 2008 23:51:32 GMT http://www.viddler.com/explore/mlanger/videos/53/comments/1 Miraz 2008-06-26T23:51:32Z
