Is it any wonder that mankind has always dreamed of flight? **Disclaimer: The mechanical means of flight using the ultralight craft, in My opinion, put undue stress on the birds you are about to see because the videographers were taking advantage of a basic instinct of the birds to fly in formation. The stress comes from trying to pit flesh and bone against a machine that does not tire. I may not have all the information and hopefully, the flights were short enough that they didn't over exert the birds. Having said all that... The images and video is stunning.
