On his return to Dayton, Orville opened a flying school at the same Huffman field[14] the Wright brothers had used for their experiments in 1904–5. Here he trained A. L. Welsh and Duval LaChapelle. When Brookins arrived there from Montgomery, near the end of May, he took on the training of Ralph Johnstone and Frank T. Coffyn, besides completing the training of Hoxsey. Two others trained at the same field later in the year were Phil O. Parmalee and C. O. Turpin. Orville Wright continued to make frequent flights until 1915, personally testing every new device used on a Wright plane. (He did not make his final flight as a pilot until 1918.) More than one person who witnessed flights at the Huffman field (or at Simms station, as the place was better known) has made comment that it was never difficult to pick Orville Wright from the other flyers, whether he was on the ground or in a plane. Students, and instructors too, would be dressed to the teeth for flying, with special suits, goggles, helmets, gauntlets, and so on; but Orville always wore an ordinary business suit. He might put on a pair of automobile goggles and shift his cap backward, and on cold days he would turn up his coat collar; but otherwise he was dressed as for the street. When he was in the air anyone could recognize who it was--from the smoothness of his flying. And when he wished to test the control and stability of a plane, he would sometimes come down and make figure eights at steep angles with the wing tip maybe not more than a few feet from the grass. The public was no longer unaware of the significance of the flights at Huffman field. Sightseers began to use every possible pretext to come as close to the planes as possible. One evening as Orville Wright was standing near the hangar, a bystander edged up to him. “I flew with Orville Wright down at Montgomery,” he declared, “and he told me to make myself at home here.” Never before having seen Orville, he had mistaken him for an employee. [Illustration: TWO ACES AND KING. Orville Wright, Wilbur Wright, and Edward VII of England at Pau, France, March 17, 1909.] Three flights at Huffman field in May, 1910, were especially noteworthy. A short one by Wilbur--one minute twenty-nine seconds--on May 21, was the first he had made alone since his sensational feats starting from Governors Island. And it was the last flight as a pilot Wilbur ever made. But on May 25 he and Orville flew for a short time together--with Orville piloting--the only occasion when the Wright brothers were both in the air at the same time. Later that same day, Orville took his father, Bishop Milton Wright, then eighty-two years old,[15] for his first trip in a flying-machine. They flew for six minutes fifty-five seconds, most of the time at about 350 feet. The only thing that Bishop Wright said while in the air was a request to go “higher, higher.”
