Were you around 50 years ago for the historic landing of Apollo 11 on the moon?
Radio communications played a vital role in the mission. When seconds count and the station you are talking to is a couple hundred thousand miles away, the importance of the "ABC's" of radio comms become clear - Accuracy, Brevity and Clarity. The mission used ground-breaking voice and data communications methods that many radio amateurs use today. (By the way, the radios used on Apollo were supplied by Collins!)
