I would like to know if there is any airplane that can routinely take off and land on a sand dune in a desert. I have searched and read about bush airplanes. Bush airplanes are used on water, river bed, grass land, ice and snow. Maybe those bush planes that can operate on snow can also operate on sand dunes, but I am not sure. The ground under the snow could be pretty firm and provide stronger support than sand dunes. Any info/comment/speculation would be highly appreciated.
