 As the designated Mercury-Atlas facility, LC-14 was thus the only Atlas pad sporting the infrastructure needed for manned launches.The first MIDAS satellites, one Atlas-Able launch, and a few more ICBM tests were conducted from LC-14 before it was completely turned over to NASA.LC-14 is most well known as the launch site for NASA's Mercury-Atlas 6 flight, which made Glenn the first American in orbit.
