We learned that birds did not control their flight by shifting their body weight, but actually changed the shape of their wings. The hardest part of builing the gliders was eliminating the tail slide phenomena when we tried to turn the plane. We discovered that the wing warping had to be used in conjunction with the rudder to make a proper turn. We made provisions for problems to minimize the risk. I came down in the water.
Proper preparation is a good replacement for reckless bravery.
We kept a lot of notes, and these notes are available at the library or book stores. I made biscuits that didn't require any milk. I also cooked meat on a gasoline fueled stove. I am just sorry I missed the start due to international date lines. There are many book about us.
