Career

Slemon joined the

His next call was to NORAD's second-in-command, Slemon, then located in Cheyenne's counterpart at CFB North Bay. While the call was being connected, the alert status went to level 4, and then 5, indicating the BMEWS site was almost positive an attack was underway, and giving Slemon the authority to order the immediate release of SAC's Airborne Alert force for attack on the USSR. By the time the call was connected, Brigadier General Harris Hull, NORAD's chief of intelligence, joined the call. After the situation was explained, Slemon asked where Khrushchev was at that moment. Hull replied that he was in New York City attending the United Nations. Slemon considered it extremely unlikely that an attack would take place that would likely kill Khrushchev, and asked Hull if there were any intelligence indications that such an attack was being prepared. Hull answered no, and Slemon broke protocol to call off further escalation of the now level-5 alert.^[3]

Slemon then ordered that the BMEWS based be contacted directly. When they did, it was discovered that the signals were indicating an attack by as many as 1,000 missiles (at that time the Soviets had four ICBMs in service) but there were oddities about the signal. In particular, the signal timing seemed to indicate the targets were at a very long distance, while the computer was reporting they were about 2,200 miles (3,500 km) away. After much confusion, it was discovered that the radar was detecting the rising Moon. On further exploration, it was found that the computer program that reported distances was dropping digits, so only the remainder of the digits were being displayed, leaving what appeared to be a credible measurement.^[3]

Slemon retired to Colorado Springs in 1964.^[2]

Slemon Park in Summerside, Prince Edward Island is named after him.^[4]
