Launch for Skylab 2 was scheduled for 9:00 am Eastern time, May 25th, 1973 and that was a bonus for me as a space-buff. First off, I got my usual parental-granted day off from “school” in order to watch and tape record the launch. Secondly, the launch time was not in network TV’s “prime-time,” and it was also not in their “daytime” broadcast period either. In fact, it was on the tail end of their morning news block and this was, indeed, “news.” Thus, there was plenty of coverage and short segments broadcast on all three networks. CBS started snippets of coverage at 7:00 am on their “Morning News” program. ABC started coverage at 8:30. Leading the pack was NBC, where the launch of Skylab 2 nearly took over their entire “Today Show” program at 7:00 am and “live” coverage began at 8:50 am. NBC’s Roy Neal and Jim Hartz ruled the roost that morning as the broadcast showed the efforts being made to save the workshop. It was clear to the news media that the wounded Skylab was sailing into unfriendly political waters. As the “Today Show” turned into nearly a two-hour, pre-launch broadcast, Jim Hartz ended with a profound observation saying,


“More than just the repair and salvage of Skylab is riding on what the astronauts do in the next two days.”


Indeed, at that point in history America’s space program and Skylab were on the downhill slide in support both in Congress and especially the White House. Any failure in the effort to repair Skylab would likely end the entire effort and the public in general would not give a wink.

At ignition, Skylab 2 appeared as if it might simply melt away the steel struts of the Milk Stool. Bright yellow-white flames burst through the legs of the giant podium and – unlike all the Saturn Vs, which we had seen held down for nearly nine seconds after ignition – the Saturn IB departed just 3.055 seconds after ignition. Then, a scant 19 seconds after liftoff, AS-206 was swallowed by the overcast. Seven seconds later a range tracking camera picked up the glow of the engine plume and held it for another 18 seconds, and that was the last anyone saw of Skylab 2’s launch. Walter Cronkite commented,

 “…I don’t think ever before has any launch disappeared quite so quickly and quite so completely…” and he was correct.

“Tower, Houston...” Mission commander Pete Conrad was ecstatic in his first call as AS-206 cleared the tower, “...Skylab 2, we fix anything, we got a pitch and a roll program!”


A few seconds later he exclaimed, “Boy is that a smooth ride!”





Being a veteran of the Saturn V boosts, the first stage of which was described as a runaway train wreck, Conrad’s words were a tip of the hat to the von Braun team at the Marshall Space Flight Center who had developed the Saturn I and IB during the early 1960s.







However, after having been in storage for a half-decade, AS-206 produced about 0.88% less thrust than predicted; the exact predicted thrust was 1,642,995 pounds and the actual thrust was 1,628,516 pounds. No matter, the S-IB first stage did its job and then staged nicely to the S-IVB, which burned for a total of 440.4 seconds. That was 2.5 seconds longer than predicted and it placed the Skylab 2 spacecraft into an orbit that was 3.927 miles higher in apogee than planned, but easily corrected.

Much to my delight, NBC news used the early morning launch to fill a bit of air time with a pre-recorded “tour” of Skylab. Spaceflight anchorman Jim Hartz did a 12-minute segment showing viewers nearly every inch of the workshop, as well as many of the devices to be used during the mission. This coverage gave me high hopes for the future mission news coverage which, as time would demonstrate, would never come to pass.





AUTHOR’S NOTE:
         As it turned out, by pure happenstance alone, Pete Conrad was exactly the right astronaut to be commanding that repair mission. Since he was a little kid he had been a hands-on, take-it-apart and fix-it guy to his soul. He loved to do hands-on work, he loved things that were mechanical and needed repair. He was probably a bit tickled that his “pure science” Skylab mission now had this repair mission as a key objective. It was his fix-it moxie that caused him to get under the line that he and Joe Kerwin had attached to that SAS wing, put it over his shoulder and then stand up, forcing it to break the SAS wing loose. That was not something they had trained to do. That was pure Pete Conrad and it saved the entire Skylab program.

APOLLO 1


This blog entry begins with an excerpt from my book, "Apollo Part One" and following that I'm going to give some perspective, so stay tuned.




"APOLLO 1
THE BLIZZARD OF ‘67

Up in the great state of Michigan we were totally unaware of the fever pitch at which the work on Apollo was progressing at Cape Canaveral and at other NASA centers around the country. In fact, on Thursday, January 26th, 1967 we were getting our first taste of a massive blizzard. After local weather broadcasters predicted, “a good amount of snow” we got plenty more than that. My Dad had driven the family car to the railroad depot in Flint about 30 miles south of our house. He was working as a railroad engineer on the “third trick” night shift at the at the Buick Fisher Body plant. This meant that he had spent all night running a switch engine in snow that began to come down far more heavily than predicted. By the end of his shift on Friday morning, the roads were impassable and the snow was coming down even harder.


Dad called home to see if we were all okay and to tell Mom that he was stranded. She was a bit scared- considering that this was the worst snow storm in a half century and she was home with three kids ages 9, 7 and 3. Dad immediately told her that he would get home- somehow.



 Of course we three kids were delighted. The schools were all closed and we watched with endless fascination as the snow blew and drifted. Eventually the drifts got so high that I could stand on a stool, crank open the bedroom window and touch the top of a drift that was right there at window level five and one half feet above the ground. Nothing moved and no one ventured outside all day on Friday the 27th, except for my Dad. The C&O line that he worked for had a freight train that came through Flint from Toledo, Ohio and ran up to Saginaw every morning. Dad hopped aboard the engine on that train and rode it up to the town of Bridgeport. There, the train passed within 100 yards of my paternal Grandma’s house. Dad had them stop there, he hopped off and hiked over the fence and through the drifts to Grandma’s house. She provided him with some warm dry clothes and hot coffee and then he set out, on foot, for our Sheridan Park home a mile and a half away. He had called from Grandma’s house to tell us he was on the way and all three of us kids kept watch out the back windows. After what seemed like hours, he came trudging along the Grand Trunk Railroad tracks behind our house and through the blizzard to our back door. We all cheered as if Santa had arrived; now we would all be snowed-in together.

That evening, as the snow piled up some folks gathered around a warm fireplace. On our side of town, however, almost no one had a fireplace and at our house we all gathered around a warm TV set. It was late in the evening and almost bedtime, we were watching ABC’s local channel 12, and my most favorite show, aside from “Batman” of course, “The Time Tunnel.” Suddenly the program was interrupted by an ABC News “Special Report.” There on the screen in glorious black and white was ABC’s “Science Reporter” Jules Bergman. Hardly looking into the camera Bergman began to read from some papers in his hands. His voice was shaking and cracked at least once- I thought he was actually going to cry, but as I listened to his words I knew why. Most of what I got from what he was reporting was that the three astronauts of the Apollo 1 mission, Gus Grissom, Ed White and Roger Chaffee, had just been killed by a fire on the launch pad at Cape Canaveral. I really did not soak in much more than that. My Mom put her hand over her mouth and gasped and my Dad said nothing. You always knew that something was really bad when my Dad went silent. Before a moment seemed to pass the news bulletin was over and the “Time Tunnel” returned.


Mom put us all to bed that evening but there was too much blizzard going on for me to sleep. I spent a protracted time looking out my bedroom window and watching the snow blow past under the street light. What kept running through my mind was that the astronauts had been killed in a fire at the pad.

“At the pad, how could that happen?” I wondered. “Were they down in the place under the rocket and someone accidentally started the engines?” my nine-year-old brain pondered, “How could NASA let that happen? Didn’t they have their spacesuits on? Aren’t astronauts indestructible?”

I kept picturing three astronauts in spacesuits walking down in the flame trench and then somehow the rocket engines just lit up and incinerated them. It was an awful thought for a kid with a very vivid imagination; almost as awful as the actual event on Pad 34."

Of course there is much more to the story, and you'll have to read the book to find out the rest. 
NOW... the blog part...

As a space buff and spaceflight historian I find that the end of January each year is simply the worst. Not because of the three U.S. manned spaceflight tragedies that took place at that time of the year, but because of the social media ratcheting up of grief over those events. Sure, we all should remember those who were lost, but let us leave it as that. Launch Complex 34, for example is treated like a grave site. It is NOT a grave site where anyone should go to weep. In fact it is a historic landmark where three astronauts were killed in an accident, but it is also the place where huge steps forward in the peaceful exploration of space took place. Certainly, in the middle of that the Apollo 1 fire also took place and three astronauts were killed. Yet we need to keep that within the total context of the history of the site.

On May 5, of 1961 Alan Shepard launched into space on a Redstone booster from the Cape and on July 21 of that same year Gus Grissom also boosted from LC-5, just 8,330 yards from where he would lose his life less than six years later. Americans were thrilled by these two flights which were boasted in the media as being a great leap in our space race with the Soviets. The Soviets, however, were quick to point out that their R-7 boosters were so much more powerful than the Redstone they made the two American space launched look like, "...a flea's jump..."

Soviet propaganda was right, yet was ignoring an American operation that was taking place right out in the open. On the same day that Alan Shepard's Freedom 7 was launched, the SA-1, S-I first stage was in the test stand at MSFC being test fired for the second time. That firing of 44.17 seconds duration produced far more power than the Soviet R-7. Some three weeks after Grissom's Liberty Bell 7 flight, that first Saturn I booster arrived at Cape Canaveral's Launch Complex 34 and was erected on the launch pedestal. It would shake the world on October 27, 1961 when it successfully launched as the world's most powerful booster.



Three more Saturn I vehicles would fly from Complex 34. The Soviets would never catch up in successful listing capability.



On August 18, 1965 the first Saturn IB would begin stacking at Complex 34 and on February 26, 1966 it would launch as AS-201, the first all-up test of the Apollo configuration. The second fully Apollo configured Saturn IB would launch on August 25 of that same year. Following its flight AS-204, the Apollo 1 vehicle would be stacked.

After the tragic Apollo 1 fire, AS-204 would be de-stacked and later used for the un-manned Apollo 5 flight that tested the Lunar Module in Earth orbit and AS-205 would be stacked at Complex 34. Notice here, that NASA did not shut down the complex after the fire and forever mark it as a grave site. Instead they did what is always done in flight test after a failure. They pressed ahead and tested the more than 800 changes to the Apollo CSM. 

Apollo 7 made history as it lifted off from Complex 34. It was the first manned flight of an Apollo spacecraft, it was the first manned flight of a Saturn launch vehicle, it saw the implementation of scores of new flight crew and pad crew safety features that would be carried forward to today. It was also the last manned launch from the Cape Canaveral Air Force Station up to this writing on January 27, 2020.

Thus, I'm not saying do not remember the Apollo 1 crew, what I am saying is as you do so also remember all of the huge leaps forward in spaceflight history that also took place at Complex 34. When you visit that site, indeed take some time to remember the crew. Then take some more time and walk around the cement base of the pad and look at the names and dates that were scrolled into the freshly poured concrete. Those men were not making a grave site, they were building a place where history would be made. Remember them as well.


Some of you reading this may think I'm crass or dismissive. No, I'm a historian and I witnessed the above stated history and the three spaceflight tragedies on TV and in person, some of which took place before some of you were even born. History, in spite of social media, must be kept in perspective. If you think that's wrong or dismissive, I'd ask why it is that you do not venture out into the desert and visit the site where Mike Adams' X-15 hit the ground killing him on November 15, 1967, less than a year after the Apollo 1 fire. He was an astronaut too. Post flight data showed that he had indeed crossed the threshold into space on that flight, and he was awarded astronaut wings after his death. 


History has to be kept in perspective.
