In the summer of 1936, OB1 was piloted by Lindsey to take Indiana Jones and Marcus Brody to Tibet while they looked for Francis Beresford-Hope. Lindsey relaxed in the plane while Jones and Brody found Beresford-Hope's Cave, and met with Alex Beresford-Hope. As the three escaped from some bandits, Lindsey heard Jones yelling, and started the plane. As the plane circled along the valley floor, it bumped over a rough rock, which caused gave a jolt to Brody, Jones, Beresford-Hope and a Tibetan Bandit who had just gotten aboard. The engines died abruptly, and the plane fell off of a cliff. Lindsey was able to restart the engines, and pulled the plane out of a dive and to safety. Flying off, the bandit was forced out with a parachute, and the plane flew to Shanghai, where Jones, Brody and Beresford-Hope left.
