If you&#x27;re interested in the concept of personal airplanes replacing commercial flight, I highly recommend &quot;Free Flight&quot; by James Fallows.<p>There&#x27;s a lot of things working against the concept.  Weather constraints and sport pilot restrictions are logistical issues, but by far the #1 issue is cost.  The Transition, Terrefugia, and A5 aren&#x27;t doing much to solve this by selling for $190-300k, so they definitely won&#x27;t be changing how the general public travels.<p>Regardless, I couldn&#x27;t be happier with my Sport License.  For now I can only afford to rent, and not much at that.  Were it not for the LSA category though, flying would still just be a wish.
