1) William R. Bertelsen is a pioneer as InventorDoc!
It is exciting to meet a pioneer of a new technology which is standard today
and who is still practising medicine at the age of 86!

click on the pictures to see his own presentation!

Here is Dr. Bertelsen in the mid 1950s ,
with his VTOL model which introduced him to the
world of the "ground effect", the basis of air cushion technology.

Watch Video 2:  The A-2000 traversing airport runways This video shows the craft doing  maneuvers on land at an airport in Illionois.  This shows the controllability of our vehicles, most unusual for a hovercraft
Note you can try a video requiring a faster Internet connection than you have. It will probably play, but Real Player will pause the video transmission periodically to "buffer" the video, and then continue.

In fact Dr. Bertelsen has been the first person flying air cushion vehicles as a person over ground and over water even before the british
colleagues did so.

It was a great pleasure for me to have a telephone call to this extraordinary and humble man. With his 86 years his voice and his ideas sound a lot younger than you ever would expect! And it started from his motive to be able to reach his patients in the countryside faster under any difficult conditions of weather and over different grounds........ He is STILL working as a medical doctor in the Trinity hospital at his town!

I definitely recommend you to spend some time on his web www.AeroMobile.com  and watch many videos, documents and pdf-files.
