The RL-10, which served as the power plant for NASA's upper-stage Centaur space launch vehicle, was the first rocket engine to use high-energy liquid hydrogen as a fuel. It has provided precisely controlled, reliable power for lunar and planetary explorations. The RL-10 embodied numerous advanced design features, including multiple use of its fuel with the "bootstrap cycle." The RL-10 is also capable of multiple restarts in space, which enables positioning of satellites or further escape of Earth's gravity.

"The development of the cotton picker was the most important single factor which enabled the American cotton industry to stay alive," observed Dr. George S. Buck, Jr., director of research for the National Cotton Council recenty. Some 96% of the 1969 U.S. cotton crop was harvested by machines, points out J.W. Wegener, manager of International Harvester's Memphis Works manager. "Old Red" was built by International Harvester in 1943, retired in 1959, and restored in 1964.
