<div class="htmlview paragraph">The object of this paper is to describe in a compressed mode the steps that have been taken, to design a prototype of the <b>TRIPHIBIAN FLYING CAR</b>, which can one day be converted into the every-man's utility car of the future. The TRIPHIBIAN should be a comfortable high performance car and amphibian airplane, that can take off and land on very short strips (STOL), be safer than most of the vehicles today, have an automatic piloting and navigation system, and be capable to operate from many land or water surfaces. In case of bad weather, when most small planes are stranded, the road driving capabilities are essential, as they are for the door to door transportation.</div>
