When I was a kid all the science magazines were talking about how everyone was going to have personal helicopters by the 1990s. You were going to be able to commute to work in your personal helicopter and land it in your back yard. It sounded like a great idea at the time. Of course, we are still a long way away from that. Some ideas sound good in theory, but fall apart due to impracticality.
I have my landing pad, but am still awaiting my helicopter.
