Flight 23. After suffering a nearly disastrous crash on July 17, the brothers completely redesigned the forward rudder (elevator), moving it further out in front of the machine and increasing its surface area. The changes paid off, and by this flight, they were able to control the airplane consistently. Orville made two complete circles with the Flyer III during a 2-minute, 45-second flight.

Their confidence in solv- ing the riddle began to relax them as well. In one entry concerning a flight on Wednesday, August 30, 1905, by Orville, Wilbur wrote that the flight was “A very comical performance.” Orville’s landing resulted in break- ing the ends of four wing ribs. There was one more problem that kept them from making even longer flights. Their accidents were not re- stricted to the problems with pitch stability. A curious loss of speed and a subsequent “arrival” in the hum- mock-filled pasture was still happen- ing with annoying frequency.
