Code Word “Hatefulness”: The Great EBS Scare of 1971

“…[My] longest five minutes in radio.”

--WOWO broadcaster Bob Sievers reflecting on what it was like to be on the air waiting to announce the end of the world.

On the morning of Saturday, February 20, 1971, Wayland S. Eberhardt, a civilian teletype operator, was going about his routine duties at the National Emergency Warning Center at Cheyenne Mountain in Colorado. One of the functions of “the Mountain” during this era was to send out the weekly Emergency Broadcast System (EBS) test directive to the nation’s radio and television stations. They were, of course, also responsible for sending out the real warning. When stations received these messages they compared it against a card to determine what action to take.   

At 7:33 a.m. local time on that fateful Saturday, Mr. Eberhardt, a fifteen-year veteran of his job, fed the wrong tape into the transmitter and set off a panic that is remembered to this day. He was later quoted by the New York Times as saying “I can’t imagine how the hell I did it.” But he did.  

The teletype message that went over the wires read:

MESSAGE AUTHENTICATOR: HATEFULNESS/HATEFULNESS

THIS IS AN EMERGENCY ACTION NOTIFICATION (EAN) DIRECTED BY THE PRESIDENT. NORMAL BROADCASTING WILL CEASE IMMEDIATELY. ALL STATIONS WILL BROADCAST EAN MESSAGE ONE PRECEDED BY THE ATTENTION SIGNAL, PER FCC RULES. ONLY STATIONS HOLDING NDEA MAY STAY ON AIR IN ACCORD WITH THEIR STATE EBS PLAN.

BROADCAST EAN MESSAGE ONE.

MESSAGE AUTHENTICATOR: HATEFULNESS/HATEFULNESS

Station managers, broadcasters and listeners across the country were thrown into a tizzy. David Skinner, the news director of WEVA in Emporia, Virginia recalled the experience for a reporter: “I thought I was going to have a heart attack trying to open that damned envelope [containing the code words that authenticate the message from Cheyenne Mountain]. I haven’t felt that way since John Kennedy was killed.”

Chuck Kelly of WWCM in Brazil, Indiana took his station off the air for twenty-two minutes and told a reporter, “I saw the authenticated message and thought, ‘My God! It’s December 7 [1941] all over again!’”

Corine Muldoon, 24, of Cambridge, Massachusetts told a Boston media outlet that she heard the alert when she was getting ready to go to work:

I couldn’t believe it. I thought it was a joke. I thought I was dreaming. Then I switched the dial and some stations were playing music, so I didn’t know what was happening. You can’t believe how panicky I was. All I could think of was Laos,* that Nixon had pushed the wrong button. I feel I lost about ten years [off my life].

Another distraught listener, Mrs. Peter Ori of Chicago, said:

I was absolutely terrified. It was so authentic. I just knew we were at war and the President would come on and say what had happened.

A spokesman for KIXL in Dallas told the New York Times that “This made us just angry as hell. You can’t play around with things like this. If we had gone on the air and broadcast this alert as being from the President of the United States, some old people would have checked in right then.”

Decades after the incident, broadcaster Bob Sievers (WOWO-AM, Fort Wayne, Indiana) referred to his time on the air after the alert as his “longest five minutes in radio.” Thanks to the folks at the History of WOWO website, these tense five minutes—Partridge Family lead-in included!—are preserved for the ages. With their permission, CONELRAD presents the audio below in a slideshow. Sievers, a Fort Wayne institution, retired from the station in 1987 and passed away at the age of 90 in 2007.   

After forty minutes of frantic scrambling and sending out “kill” messages that did not contain an authenticator code word, the Cheyenne Mountain staff finally found the correct code to cancel the apocalyptic transmission. It read:  

MESSAGE AUTHENTICATOR: IMPISH/IMPISH

CANCEL MESSAGE SENT AT 09:33EST REPEAT CANCEL MESSAGE SENT AT 09:33EST

MESSAGE AUTHENTICATOR: IMPISH/IMPISH

20 FEB 10:13EST

President Nixon did not comment of the gaffe, but his Secretary of State, Melvin Laird, stated that there would be an investigation of what caused the false alert. The Pentagon released this statement that blamed civil defense:

The Office of Civil Defense is currently investigating the circumstances surrounding the transmittal of the erroneous message. The National Emergency Warning System is located within the NORAD Cheyenne Mountain complex but is not a NORAD function. It is operated by the the U.S. Army’s Strategic Communications Command. This is a civil defense action and not a military one.

Louis I. Smoyer, the chief of the warning center, said simply, “It damn sure won’t happen again. I’ve got to have time to sit up here and figure out how to make this thing fail safe.”

To his credit, Smoyer’s solution did not involve firing the hapless Wayland S. Eberhardt who was described as being “seriously shook up” over his mistake. Rather, the manager had a simple, low-tech remedy: He moved the tapes for the genuine alerts away from the transmitter. The Greeley (Colorado) Tribune explained the new procedure to its readers on February 23, 1971:

…In the past three tapes, one for the test and two for actual emergencies, were hanging on three labeled hooks above the transmitter… In the future only the test tape will be left near the transmitter. The two emergency tapes [will be] be sealed in clearly marked envelopes and placed inside a nearby cabinet. 

This decidedly analog fix seemed to work. And it appears that Mr. Eberhardt lived out the rest of his life in quiet obscurity. He died in Colorado Springs, Colorado on November 20, 1996. But in Cold War trivia circles, he will never be forgotten.
