This fear was confirmed by Capcom Ed Mitchell; they were, indeed, 0.5 miles (0.8 km) or more south of track. Scott knew that, even with the rover, this might impair the effectiveness of their explorations. During those final moments, he clicked his hand controller 18 times, forward and to the side, adjusting their trajectory to bring Falcon back onto its prescribed path. Those seconds were so unreal—the clarity of the scene, the weird behavior of the lunar dust, the strange, almost-unpowered sense of drifting like a snowflake through the majesty of the lunar mountains—that Irwin mentally convinced himself that he was still in the simulator back in Houston. If he had admitted to himself that this was for real, he felt that he would have been just too excited to do his job properly. Yet if this was a simulation, it was one of the smoothest that he had ever flown. They were very close to the surface now and lunar dust obscured the landing site entirely, like a thick fog. It was only Irwin’s call that the blue Contact Light had illuminated which finally convinced them that they had touched down. The time was 6:16 p.m. EDT on 30 July 1971 and, with a firm thud, the seventh and eighth men from Earth reached the surface of the Moon. “Okay, Houston,” radioed Scott, “the Falcon is on the Plain at Hadley!” His reference to the landing site as a “plain” paid due tribute to Scott’s alma mater, the Military Academy at West Point, whose parade ground was also nicknamed “The Plain”. What did cause concern was that Falcon had come down on uneven ground and one of its rear footpads had planted itself inside a small crater. (Mission Control would later call their lander “The Leaning Tower of Pisa”, an epithet which Scott did not appreciate!) Irwin remembered the landing as the hardest he had ever been involved in; “a tremendous impact with a pitching and rolling motion. Everything rocked around and I thought all the gear was going to fall off. I was sure something was broken and we might have to go into one of those abort situations. If you pass 45 degrees and are still moving, you have to abort. We j
