“In my last flight, the machine was devoid of its steering apparatus which I was not aware of until I had ascended in it. My airship can be steered by a rudder or by having one of the propellers revolve faster than the other, on the principle of a twin screw steamer.”

„The fact was that it was an experimental trip and the machine was in the rough. I did not have steering apparatus that was adequate, and, seeing a good place to descend, I did so. Now I shall either have a large rudder on the new ship or else perfect my twin screws so that I can revolve one faster than the other to cause it to steer the machine. It will be on the same principle as twin screws work on an ocean vessel.”

"Suppose there were a horizontal rudder [elevator] in front of our flying machine which could be set at any angle, up or down; now, if the machine was in motion and the air stationary, and the plate set at an upward angle, then the corresponding upward thrust would certainly cause the machine to rise at an upward course until the same plate is again set horizontal. It will also cause the machine to descend if you set the plate at a downward, slanting angle. So there we have a very effective way of steering a flying machine, up or down and also provide for longitudinal stability, providing the speed of the machine is high; And as for steering on either side, a vertical rudder may be used with the same effect.

The reason a flying machine has never been steered is because they have insufficient power and therefore insufficient speed and are just the same as a steamboat lying in quiet water. Without any motion to either water or steamboat, it cannot be steered."

„On the second trial it started from the same place and sailed with myself on board across Long Island Sound. The machine kept on steadily in crossing the wind at a height of about 200 feet , when it came into my mind to try steering around in a circle. As soon as I turned the rudder and drove one propeller faster than the other the machine turned a bend and flew north with the wind at a frightful speed, but turned steadily around until I saw the starting place in the distance. I continued to turn, but when near the land again, I slowed up the propellers and sank gently down…”
