Well this turned out to be a whole lot easier than I expected. A quick Google (Not GIS) of "African amphibious vehicle", and there it is on the first page, although you have to Google "Nigerian amphibious vehicle" to get the image. The puzzle vehicle is the invention of 39 year old Nigerian inventor Mr. Kehinde Durojaiye Obasanjo. It is called the: air-Amphibian jet, and the inventor claims it will be able to fly as well as run on land and water. According to the inventor, the current model is limited to land and water due to his lack of funds to incorporate the equipment necessary for flight.
Personally, after studying the photograph, I'm not sure that I would want try this vehicle on water, at least not without a good life jacket, let alone fly in it.
