This 1966 MIT Science Reporter television program details the development and construction of the Lunar Excursion Module (LEM), the only vehicle of the three Apollo spacecraft modules that actually lands on the moon. Project engineer Thomas Kelly gives a tour of the LEM at Grumman Aircraft in Long Island, NY, and demonstrates the LEM Automatic Checkout System, while test pilot Robert Smyth demonstrates the lunar landing simulator via an electronic computer-controlled model of the Moon. The program is presented by MIT in association with WGBH-TV Boston, and hosted by MIT reporter John Fitch; it was produced for NASA. MIT Museum Collections.
