I didn't realize that Friday, January 28, 2011, was the 25th anniversary of the Challenger explosion until I saw a tweet mentioning that Friday morning. It immediately brought back memories of that day in 1986 when I was at work when an administrative assistant first brought word that Challenger had exploded shortly after takeoff. Everyone’s reaction, including mine, was “What? That isn't possible!” Shuttle launches had become routine in our minds.
We found a TV and tuned in a network news special coverage just in time to see a replay of the liftoff and flight until the horrific explosion after 73 seconds. It seemed like watching a movie since this couldn’t really be happening.
My other memory of that day is the difficult yet graceful address to the nation given by President Ronald Reagan bringing tears to my eyes. But through the years the tragedy fades from memory a little more each year until January 28 comes around again and we are again reminded of Challenger and Christa McAuliffe in particular. But my memories of Challenger and its crew were rekindled in July 2007 when my wife and I vacationed in Florida to visit our oldest son who lives in Gainesville . While there we decided to visit the Kennedy Space Center and it is a day that I will always remember.
As a child I was really interested in space and it was a very exciting time for that. I remember Sputnik, Telstar, the Mercury, Gemini, and Apollo programs, including Neal Armstrong’s first step on the moon, and Apollo 13. So when we got to the Kennedy Space Center I was totally wrapped up in every aspect of every step we took there. One of the most amazing memories of that day was the opportunity to walk below every stage of the Saturn 5 moon rocket and still be totally amazed at how huge it is with over two million systems and sub-systems that never experienced a single failure of any rocket system during the history of the program. The first stage generated seven and a half million pounds of thrust, one and a half million from each of its five engines. Other lasting impressions were the huge vehicle assembly building, the crawler tracks from there to the launch pads, and seeing Shuttle Endeavor (STS-118) on Pad 39A being prepared for its launch on August 8, 2007 just two weeks after our visit. I watched that launch and especially its landing with increased interest and awareness as I saw the shuttle land where we had been parked along the runway just weeks earlier.
The most remarkable experience of the day was the Shuttle Launch Experience and I even got the T-shirt too. My son and I went for the “ride” and I would do it again in a heartbeat given the chance but I no longer qualify due to high blood pressure. The requirements and restrictions are very specific. We had to remove and put in lockers every loose article, including baseball hats, and empty everything from our pockets to avoid FOD (Foreign Object Debris) before being allowed to enter. In short we were going to “ride” the shuttle simulator to experience the final minute of the shuttle countdown and the first few minutes of shuttle flight.
The first thing that we experienced after we were positioned and belted into our seats was the feeling of being rotated back flat on our backs and then the countdown resumed. Then as explained to us beforehand, when we reached T minus 6 seconds we heard and felt the vibration of the rocket engines roaring to life and the “twang” before we lifted off with an acceleration I have never felt anywhere else. It was totally exhilarating. Also, as explained beforehand, when the roll program executed to place our shuttle upside down below the main booster, we never felt the sensation of being upside down at all because we are accelerating so rapidly, all we could feel was being accelerated faster and faster as we experienced up to three Gs. Our speed is displayed to us as it is increasing rapidly but I don’t remember how fast we were moving as we approached one minute of flight and what is known as Max Q of dynamic forces against the shuttle. Once beyond that point is where the command is given for Throttle Up and when that happens you definitely feel a real kick above and beyond the acceleration that you are already experiencing and that is when Challenger exploded after 73 seconds of flight so for me that was a pretty dramatic recall of the Challenger disaster during my Shuttle Launch Experience.
Our flight continued with the jettisoning of the Solid Rocket Boosters and eventual entry into space and a momentary feeling of weightlessness just before our experience ended as I was looking out our window passing over the Adriatic Sea .
The Shuttle Launch Experience was a thrill. I will always recommend a stop at the Kennedy Space Center and the Shuttle Launch Experience to anyone who visits central Florida . It is an experience that I will never forget and it was brought back to me very vividly in my memory again last Friday.
