Neil Armstrong was involved in several incidents that went down in Edwards folklore and/or were chronicled in the memoirs of colleagues. The first was an X-15 flight on April 20, 1962, when Armstrong tested a self-adjusting control system. He flew to a height of 207,000 ft (63 km), (the highest he flew before Gemini 8), but he held the aircraft nose up too long during descent, and the X-15 bounced off the atmosphere back up to 140,000 ft (43 km). At that altitude, the atmosphere is so thin that aerodynamic surfaces have almost no effect. He flew past the landing field at Mach 3 (2,000 mph, or 3,200 km/h), over 100,000 ft (30.5 km) altitude, and ended up 40 miles (64 km) south of Edwards (legend has it that he flew as far as the Rose Bowl). After sufficient descent, he turned back toward the landing area, and barely managed to land without striking Joshua trees at the south end. It was the longest X-15 flight in both time and distance of the ground track.[30]
Four days later, Armstrong was involved in a second incident, when he flew for the only time with Chuck Yeager. Their job, flying a T-33 Shooting Star, was to test out Smith Ranch Dry Lake for use as an emergency landing site for the X-15. In his autobiography, Yeager wrote that he knew the lake bed was unsuitable for landings after recent rains, but Armstrong insisted on flying out anyway. As they attempted a touch-and-go, the wheels became stuck and they had to wait for rescue. Armstrong tells a different version of events, where Yeager never tried to talk him out of it and they made a first successful landing on the east side of the lake. Then Yeager told him to try again, this time a bit slower. On the second landing they became stuck and according to Armstrong, Yeager was in fits of laughter.
On May 21, 1962, Armstrong was involved in what Edwards' folklore called the "Nellis Affair". He was sent in an F-104 Starfighter to inspect Delamar Lake, again for emergency landings. He misjudged his altitude, and also did not realize that the landing gear had not fully extended. As he touched down, the landing gear began to retract. Armstrong applied full power to abort the landing, but the ventral fin and landing gear door struck the ground, which damaged the radio and released hydraulic fluid. Without radio communication, Armstrong flew to Nellis Air Force Base, past the control tower, and waggled his wings, the signal for a no-radio approach. The loss of hydraulic fluid caused the tail-hook to release, and upon landing he caught the arresting wire attached to an anchor chain, and careened along the runway dragging the chain. It took thirty minutes to clear the runway and rig an arresting cable. Armstrong telephoned Edwards and asked for someone to collect him; Milt Thompson was sent in an F-104B, the only two-seater available, but a plane Thompson had never flown. With great difficulty, Thompson made it to Nellis, but a strong crosswind caused a hard landing and the left main tire suffered a blowout. The runway was again closed to clear it, and Bill Dana was sent to Nellis in a T-33 Shooting Star, but he almost landed long — and the Nellis base operations office decided that it would be best to find the three NASA pilots ground transport back to Edwards, to avoid any further problems
