Carl Mortenson - Designer - As he served with a mission aviation organization as
a bush pilot/mechanic in South America, he realized there was a need for a safer, more useful STOL aircraft, but finding limited
numbers from which to choose.
of the STOL aircraft were single-engine planes that were slow and unable to carry large loads. This prompted Carl to endeavor
to design an aircraft that could not only get into short rough airstrips, but that could also carry a good load and have the
speed and safety of a high performance twin.
to the States in the early 60's, yet with no formal education in aeronautical engineering, designed and built a high-wing
prototype, which led to the final produced Evangel 4500.
