Second Space Shuttle Launch Remembered (Part 2)

I WAS THERE… Only This Time I Was Closer - Part 2

By Wes Oleszewski

When last we left me at KSC, the space shuttle Columbia was poised for its second launch and I found myself as an NIP, (Non- Important Person) observing at a place called Bunker number 7 among a group of VIPs. One of those was a very kind lady who took pity on me, the impoverished college student, and gave me an STS-2 souvenir postal cover to send my folks. Inside the cover was a small note card sized sheet that was blank on one side and gave some common space shuttle facts on the other side. I took a moment to scribble a note to my folks on the blank side, also denoting that the countdown was currently at T-2:00:08 and counting. Dropping the note card into the cover I happily trotted to the portable post office and mailed the envelope that one day may become "… a collector's item."

Joe Engle and Dick Truly were strapped aboard the Columbia at about that same time. To most of the public they were unknown rookies who had never flown before and space, but to us spaceflight buffs these two pilots were far from being rookies. Engle, in fact, was already an astronaut who had flown in space before even he joined NASA. He had flown the X-15 a total of 50 times between 1963 and 1965 with three of those missions reaching altitudes above 50 miles. This qualified him to wear astronaut wings. Additionally Engle and Truly actually had a one up on the first shuttle crew, Young and Crippen. To date Young and Crippen had performed one landing of a shuttle orbiter, but the crew of Engle and Truly had already performed two landings of a shuttle order. In 1977 Engle and Truly were two of the four pilots who flew the space shuttle Approach and Landing Tests with the orbiter Enterprise.

Glued to assorted portable radios and at least one portable TV, we monitored the count as it was broadcast by various local news stations. When the count neared the planned time to come out of the scheduled T-9:00 hold, Launch Director George Page elected to take a moment before resuming the count. It was his intention to keep his controllers cool, take a deep breath and make sure they were doing everything right. That little bit of extra hold time, however, really annoyed some of the newsman- of course that meant nothing to the launch director. After just a few short minutes the count resumed in the Columbia had the undivided attention of several million of people around the world.

After the previous week’s scrub nearly everyone seemed to be hypersensitive to the T-31 second mark in the count. As that point came and went a cheer and applause echoed through the crowd. Apparently everyone seemed to have the perception that if you got past that moment in the count you were good to go. In fact, I noticed for many years that passing the T-31 seconds mark and the start of redundant sense sequencing tended to draw a smattering of applause. The cold hard truth was that it meant nothing more than detection of problems were turned over to the computer and thus, anything that would keep you from flying could not be detected several million times faster then when you are off the sequencer. So there was really nothing to cheer about.

In the final seconds prior to the launch I went and stood on the bleachers with the real VIPs. The guy standing next to me was armed with a Super 8 movie camera. At main engine start he raised the camera to his eye, pulled the trigger and began filming. I guess he didn't expect what those of us who had been there for the previous shuttle launch had already experienced. A few moments after SRB ignition the shuttle reached out and grabbed us compelling everyone scream "GO BABY, GO!" A moment later I glanced over to see the guy, mesmerized and standing there looking up at the departing shuttle, his mouth hanging open and his hand with the running movie camera down at his side- filming the bleachers. I nudged him with an elbow and got his attention then pointed down at the camera."OH!" He said as he returned to filming the launch. For some reason the shuttle did that kind of stuff to you.

A little more than 8 minutes later the United States had accomplished something never before done- they had reused a manned spaceflight vehicle. Columbia was safely in orbit and soon we were safely back aboard the bus- feeling that strange sense of pride, as if we had launched Columbia ourselves.

Although STS-2 made it safely to orbit, this was still a test flight and things were still expected to go wrong… thus they did. One of the three fuel cells on board the orbiter failed early in the mission. That fuel cell was shut down and isolated. In the process of doing that mission control was forced to alter the mission profile from a five-day flight to a two day flight. The crew elected to double their work efforts and managed to accomplish nearly 90% of their scheduled tasks in the shortened mission. Then they set the Columbia up for landing at Edwards Air Force Base on November 14th.

One of the landing objectives in the STS-2 test flight was to attempt the first crosswind landing of the Columbia. Mission planners had their fingers crossed that the winds for this landing would be a bit stronger than the calm conditions that existed in the previous shuttle landing. The old saying of "be careful what you ask for, because you just might get it," held true for STS-2. NASA planners got their wind-in fact, they got a lot of wind. As the orbiter was coming into a reentry blackout, John Young was busy performing landing approaches in the Shuttle Training Aircraft on the crosswind runway. On his final pass to that runway he found the winds to be a direct crosswind at 12 to 19 knots- and that was far more than NASA was comfortable with for the test. They changed the runway, but that meant that when the orbiter made its turn to final approach at altitude, it would be turning into a 90 knot wind. Some quick recalculation's of energy management on final approach were required. Additionally, one of the tests was to fly this portion of the approach on the automatic flight control system and that meant that when turning into a 90 knot wind, the autoland would try to over bank and pull a few more G’s the NASA was comfortable with. So, Engle would simply have to skip that portion of the test, come out of the autoland mode, make the turn on manual and at his option return to autoland.

By the time STS-2 was on its final approach the winds on the surface were gusting to over 25 knots. Of course this crew had already made two previous free flight landings and approaches at Edwards in the orbiter Enterprise and were already the most experienced landing crew in the astronaut office. Engle and truly guided the Columbia to a perfect landing and they along with all of NASA succeeded in accomplishing yet another never before performed technical achievement. For the first time a manned space vehicle had been successfully re-launched, re-landed and re-used.

Now, 30 years after the flight of STS-2, I still have that "collector's item" postal cover that I sent to my folks. I figure it’s worth about $1.75. And so to celebrate that event I took it out, sat it on my desk and remembed the launch and the kindness of that nice lady who took pity on an impoverished college kid that day. I even bought some cheap strawberry preserves, just so I could make a well-squished peanut butter sandwich. It strikes me that at every space shuttle launch, in fact every manned spaceflight launch, pleasant people gather in a completely joyful atmosphere- people just like that lady. You can ask yourself how often is it that anywhere in America crowds of people, upward of a million at a time, from all different backgrounds, gather in one place and they are all happy, proud, pleasant and friendly. Without any taking of sides, protesting, political smears, hatred, vilification, damage and violence- they come only to witness and celebrate the peaceful advancement of human civilization. This perhaps is the most overlooked benefit of United States human spaceflight. With the end of the shuttle, this witnessing and celebration the spectacle of that peaceful advancement of our civilization is quite likely to be the one thing that we will all miss the most in the years ahead.
