Kent State shootings May 4, 1970.
The Cuban Missile Crisis is one of my earliest memories. My father was a supply sergeant at Blytheville Air Force Base, Blytheville, Arkansas. I remember this time because Daddy had to stay at the base since they were on alert. I remember standing in my parent's bedroom watching my mother put bottles of water in their closet. She used empty bleach bottles to store the water. I must have asked why she was doing that. I vaguely remember her saying something about the crisis and Daddy being at the base. In October, 1962 I was 2 months shy of being 4 years old.
Following information is from this article:
"The 97th BMW earned an Air Force Outstanding Unit Award (AFOUA) for activities during the Cuban Missile Crisis in 1962. On 22 October SAC responded by establishing Defense Condition Three (DEFCON III), and ordered the 97th to place two B-52s on airborne alert. Tension grew and the next day SAC declared DEFCON II, a heightened state of alarm. While at DEFCON II the 97th maintained two B-52s on airborne alert. One of the 97th's bombers carried AGM-28 Hound Dog and ADM-20 Quail missiles, the other carried nuclear and conventional ordnance. No missions were aborted or canceled during the crisis. The 97th and other units deployed KC-135 tankers to Zaragoza Air Base, Spain to refuel the alert force. Reconnaissance photographs taken on 1 November 1962 indicated that the Soviets had begun dismantling the SS-4 IRBM missile sites in Cuba. The wing returned to DEFCON III on the 15th and subsequently resumed normal activity on 20 November."
**"Known for most of its operational life as Blytheville Army Airfield (1942–1946) or Blytheville Air Force Base (1953–1988), the facility was renamed Eaker Air Force Base on 26 May 1988, in honor of General Ira Eaker, an air pioneer and second commander of Eighth Air Force during World War II."
June 5-10, 1967 Six Day War in Israel; June 5, 1968 Assassination of Bobby Kennedy
The original list is good, but has some tech introductions that I doubt most Boomers would have noticed at the time (though they definitely made impact on our lives). I agree with adding the Kent State shootings, the Cuban Missile Crisis, assassination of Bobby Kennedy, the Six Day War that others have mentioned. I am writing this on the 20th anniversary of Princess Diana's death 31 August 1997, which certainly affected a lot of Boomers. Some might add the death of Malcolm X. What about The Beatles on Ed Sullivan? The Vietnam War protests (more broadly than Kent State) and the Chicago Democratic National Convention in 1968 that all but tore the country apart? Watergate and President Nixon's resignation?
