On this day in history, Jan. 28, 1986, the space shuttle Challenger — scheduled for a routine launch from Cape Canaveral in Florida — exploded after just 73 seconds in flight, killing all seven Americans on board.
The disaster shocked the nation — and led to an immediate pause in the space shuttle program.
The cause of the disaster was found to be the failure of the primary and secondary redundant O-ring seals in a joint in the shuttle's right solid rocket booster (SRB).
While the mission on that fateful day in 1986 was supposed to be like any other routine mission,

Related to the temperature at launch. Completely avoidable if the decision makers had viewed the oring failure data as a function of temperature and realized that at the temperature of the launch the oring failure was likely to be 100%. Instead they viewed the oring failures as a function of launches. Data presentation is an art.

Columbia, Challenger and Apollo 1's disasters all happened on different years but in the same 7 day week period.

Read and understand Edward Tufte books on "visual display of quantitative data". Three volumes that should be required study by all engineers who must present data to management.

Both space shuttle disasters were caused by stupidity, arrogance, and politics. Anyone with have a brain knows that different materials expand and contract very differently when exposed to temperatures so much colder than normal causing the fuel leak that destroyed Challenger. The other shuttle was destroyed by replacing glue that actually held the tiles on with "environmentally friendly" glue demanded by so-called environ"mentalists" because it was politically friendly.
Neither should have happened.

I had the tv on in my classroom anxiously awaiting this event with my 30 sixth grade students. They were hoping to ask questions of one of the astronauts. As soon as the explosion occurred I was stunned and had to turn off the tv and calm very anxious students. I’ll never forget it as long as I live.

Months leading up to the Challenger, NASA offered applications to be the "First Teacher in Space." I sent for one and still have it (Never sent it in). Maybe it will be a collector's item someday.

I was working and someone came into the room and said that the Shuttle had exploded. We all thought they were joking until the radio broke through with the news. After that, it was all anyone could talk about. One of those days, like 9/11 or OKC where you never forget the details or where you were when you found out.

This was the big, shameful black mark on Reagan's administration.
I believe President Reagan was giving the State if the Union that eveniing, and his staffers wanted to be sure to have the teacher in space that evening, which in itself was just politics, since she was a social studies teacher, not a STEM teacher. (NASA chose her because she was glib)(and affable)
My teens displayed the coldness that only a teen could dislay.
They called the launch a method for making ChristaMcAuliffeburger.

Back in the day when Americans were more united. I remember it well.

This same mentality continues today. Damn the facts, it's results and money we want.

I was sitting in class at U Lowell when the prof announced the tragedy.
Another of my professors, statistics teacher, was the brother of Roger Boisjoly, the NASA engineer who predicted the oring failure and was ignored by NASA execs.
This teacher used the tragedy to demo the power of statistics to predict and make informed decision. As well as the culpability of gvt officials for ignoring the data and greenlighting the launch.

When Challenger blew up I was with 150 professional golfers at a mini-tour (Florida Tour, a tour I cofounded) event some 35 miles away. Because the putting greens were frosted in the freezing temperatures of early morning, we couldn't tee off beginning at 7:30 as planned, and had to wait until 11:45, by which time the greens were thawed and ready to take footprints. Because we had lost the entire morning, the whole field had to start at the same time, off all eighteen tees, in a shotgun start. When Challenger blasted off, most everyone was either on the practice putting green or the practice tee. The day was brilliantly sunny, without a cloud in the sky all day long. Seventy-three seconds into the flight, the shuttle exploded, and the contrails crossed. A player standing next to me, an Orlando native, had seen dozens of successful takeoffs from his back yard, and he immediately knew Challenger had exploded. "Oh, man. That thing just blew up!" he said. A moment later someone ran out of the clubhouse and announced what we all feared.
There was nothing left in the sky except smoke. I barely heard anyone say anything that day. Just silence from every player as he played his competitive round. Five hours later, the tournament wrapped up and the checks written, as I headed back to Tarpon Springs with my best friend and business partner, the smoke from the explosion was still there above us, obvious. Haunting. Still not a cloud visible. Just blue sky and smoke from the explosion. No one who saw it will ever forget it.
