[quote=Wolfman]Isn't the prop on a plane a 'really big fan'? And aren't the wings, sails? Seems to me if a plane can take off from a treadmill then a sailboat can blow itself. Although I think it would be much more fun to have someone else do the blowing. :-P<!-- editby --><em>Edited by Wolfman on May 12, 2011 - 12:37 PM.</em><!-- end editby --> [/quote]
