ABOUT THE AUTHOR:

Stephen duPont has written and published several aviation books and papers, written articles in
A0PA Pilot and EAA Sport Aviation.  His first aviation writings appeared in
The Soaring Bulletin
in 1935, predecessor of the magazine SOARING, published these past 70 years by the Soaring
Society of America, Inc.

His publications include:
Soaring by the Numbers, Soaring Accidents That Almost Happened,
Staying Safe in Sailplanes.
  A paper, Safer Landings Through Understanding Visual Pattern
Angles,
was read before a meeting of the Soaring instructors, one of whom was the astronaut
Storey Musgrave.  Musgrave was later quoted on the Larry King Late Night Show, saying that
duPont's paper played an important role in learning to land the space shuttle.  At least one of
his books has been published in later years by the Soaring Society of America.

In his freshman year at MIT in 1934, duPont met Heraclio Alfero when the latter's engine was on
test there.  It had been built in Springfield, MA by the Indian Motorcycle Company, of which
duPont's father was president at the time.


duPont is a commercial pilot and an FAA  Aircraft and Powerplant Mechanic, having held a
pilot's license since 1935.  He is rated to fly single engine land and sea airplanes, gliders and
helicopters.  As he writes this book, he is in his 91st. year.

The Spanish Pilot, Heraclio Alfaro was
knighted at age 18 by King Alfonso III for
designing, building, and flying Spain's first
Airplane.
ABOUT THE BOOK:

Steven duPont spent many years yearning
to put the information he had into a form
that could be used by others to continue
experimentation with this type of engine,
convinced it can be a step forward,
especially in efficiency.

The book is filled with many personal, and
frequently amusing, anecdotes relating to
family, friends, and coworkers, all of whom
contributed to his association with the
Spanish inventor and his engine.  Even the
novice can marvel at the steps involved in
obtaining patents

There are many diagrams for the engineer
who would like to pick up on the idea and
perhaps carry it further into the future.

Aside from the mechanical aspects of the
book, duPont also tells of his life-long
combat with blindness - sometimes beating
it, sometimes being overtaken through a
series of accidents and recoveries.  Right
now, the accidents are winning, but let him
tell the story.

As you can see from the biography above,
duPont "knows his stuff" and has shared it
in a very clear and readable way.
