Orville made a short flight on September 7, and two flights the next day; one of eleven minutes, ten seconds; the other of seven minutes, thirty-four seconds. On the morning of September 9, he circled the field fifty-seven times in fifty-seven minutes, twenty-five seconds. Later in the day, he circled the field fifty-five times in one hour, two and one-quarter minutes. Then he surprised and delighted his friend, Lieutenant Frank P. Lahm, by inviting him to go with him for a flight. They were in the air six minutes, twenty-four seconds, and circled the field six and one-half times. All three of these flights on the ninth established new world endurance records; two of them for flights with pilot alone, and the third for pilot with passenger. Orville made a flight of one hour, five minutes, fifty-two seconds on September 10, rising to a height of 200 feet and exceeding the world endurance record made by himself the day before. On the next day he again broke the one-man endurance record by flying for one hour, ten minutes, and twenty-four seconds, while circling the field fifty-seven times and describing two figure eights. On the twelfth, he increased the two-man endurance record by taking with him Major George O. Squier, Acting Chief Signal Officer, for a flight of nine minutes, six seconds. Immediately after that, Orville made a flight alone. He circled the field seventy-one times in one hour and fifteen minutes--again breaking the endurance record for one-man flight. It was estimated that he reached a height of 300 feet.
