Mike Mullane - Riding Rockets

After the White House learned of the O-ring history, it concluded there was no way NASA could conduct an impartial investigation into itself. President Reagan ordered the formation of the Roger’s Commission to take over the investigation. (The commission was named for its chairman, former attorney general William P. Rogers.) As I followed their reports, I learned that my rookie flight, STS-41D, had been one of the fourteen O-ring near misses. In fact it had been the first to record a heat blow-by past a primary O-ring. As Bob Crippen had said, “Whatever it was, we’ve all ridden it.” I wondered why STS-51L had been lost and not 41D? Would the “bump” of just one more max-q shock wave on Discovery ’s flight have opened the SRB joint seal enough for total O-ring failure and death? Only God knew that answer. But on August 30, 1984, the breeze from Death’s scythe had fanned my cheek.

In the weeks after Challenger I went to work each morning wondering why. I had nothing to do. A handful of astronauts were appointed to support the Roger’s Commission but I wasn’t one of them. My phone rarely rang. There were no payload review meetings to attend, no simulations to fill the hours. In the astronaut office safe was a preliminary copy of my classified STS-62A payload operations checklist, something I had been devouring in my pre- Challenger life. But now it sat abandoned. I saw no reason to continue my training for the Vandenberg mission. It was obvious the shuttle would not fly for a very long time and when it did it wouldn’t be from California. Rumor had it the USAF was going to bail out of the shuttle program altogether and go back to their expendable rockets. They had never been fans of launching their satellites on the shuttle in the first place. Congress had rammed that program down their throats. The air force had rightly argued that when expendable rockets blew up, they could be fixed and returned to flight status within months, whereas the human life issue of manned vehicles could delay their return to flight for years. During that lengthy delay national defense could be jeopardized. That was exactly where Challenger had put the air force. It was easy to believe the rumors that the air force was going to walk away from their investment in the Vandenberg shuttle pad.

There was also a very big technical reason Vandenberg was dead. Because rockets being launched into polar orbit lose the boost effect of the eastward spin of the Earth, they cannot carry as much payload as eastward-launched KSC rockets. To recover some of that payload penalty, NASA had developed lightweight, filament-wound SRBs for use on Vandenberg missions. If Thiokol had been unable to seal a steel booster, the thinking went, how much more difficult would it be to seal one made of spun filament and glue? No one expected the lightweight Vandenberg SRBs to be certified now. The space shuttle would never see polar orbit, and neither would I. I removed the Vandenberg photo from my wall and placed it in the bottom drawer of my desk. I didn’t want to be reminded.

It was impossible to escape the torment that was Challenger. In a walk down the hall my eyes would catch the 51L office nameplates. On a visit to the mail room I encountered the staff moving the Challenger crew photos to the “Deceased Astronauts” cabinet. I wanted to cry. I wanted to stand there and just weep. But the Pettigrew in me denied that release.

The flight surgeon’s office informed everybody that Dr. McGuire—one of the psychiatrists who had interviewed us during our TFNG medical screening, in what now seemed like a different life—would be available for counseling. Some of the wives sought his therapy, Donna included. Most people in my mental condition would have jumped at the opportunity for some help. But most people were not astronauts. I was dyed through and through with the military aviator’s ethos that psychiatrists were for the weak. I was an astronaut. I was iron. So I held it all in. If I could hold an enema for fifteen minutes, I could hold all this in and deal with it myself. I would cure myself of depression or survivor’s guilt or post-traumatic stress syndrome or whatever it was that ailed me…probably all of the above.

Six weeks after Challenger, NASA announced they had found the crew cockpit wreckage in eighty-five feet of water. It contained human remains. I had been hoping the wreckage would never be found, that the cockpit and crew had been atomized at water impact. If it had been me, that’s how I would have wanted it. Let the Atlantic be my grave. But as shallow as the wreckage rested, NASA had no option but to pull it up. Otherwise it would eventually be snagged on a fishing net or discovered by a recreational diver.

Having been at an aircraft crash site, I suspected the condition of the remains was horrific. The cockpit had been sheared from the rest of Challenger , and after a 60,000-foot fall had impacted the water at its terminal velocity of nearly 250 miles per hour. At that speed the Atlantic would have been as unyielding as solid earth. I couldn’t imagine the remains would allow the pathologists to learn anything. And I was equally certain nothing relevant to the tragedy would be discovered on the voice recorder, even if it was in good enough condition to be read. Dick Scobee’s “Go at throttle up” was uttered only a couple seconds prior to breakup and there was nothing out of the ordinary in his call. Obviously he and the rest of the crew were unaware of their problem. And nothing could have been recorded after breakup because the recorder lost electrical power and stopped at that instant. Not that there would have been anything to record. I remained convinced the crew had been killed outright or rendered unconscious when Challenger fragmented.

After the remains were removed, TFNG Mike Coats and several other astronauts examined the wreckage. Mike returned to Houston with the comment, “The cockpit looks like aluminum foil that had been crushed into a ball.” It was largely unrecognizable as a cockpit, a fact that didn’t surprise me. He added, “I saw a few strands of Judy’s hair in the wreckage…and I found her necklace.” He didn’t have to say any more. I knew the necklace. Judy always wore it…a gold chain with a charm displaying the two-finger-and-thumb sign language symbol for “I love you.” She had a hearing-impaired family member and the necklace was a display of her support for those with similar handicaps. The image Mike’s words conjured would not leave me. Like the flash of a camera, I continued to see it no matter where I looked—the crushed cockpit, Judy’s hair, her necklace.

The remains were held at Cape Canaveral Air Force Station for pathologists to identify. A few weeks later I watched NASA’s TV broadcast as a procession of hearses drove onto the KSC runway and unloaded seven flag-draped caskets. Each was accompanied by an astronaut. A military honor guard reverently carried the remains into the belly of an air force C-141 transport aircraft. There was no dialogue to accompany the TV footage. The silence made the images even more heartrending. The camera followed the plane as it rolled down the runway and receded to just a dot in the sky. The Challenger crew was finally returning to their families.

On May 19 a horse-drawn caisson slowly bore the remains of Dick Scobee toward his final resting place in Arlington National Cemetery. The day was sultry and the air tinted with the odor of horse dung and freshly mowed grass. A military band, playing a medley of patriotic arrangements, led our procession. A formation of skin-headed GI pallbearers, dressed in mirror-polished livery, marched with them. Another group of buzz-cut soldiers bore the American flag and other standards streaming blue and red battle ribbons. Rivulets of sweat poured into their eyes from under their headgear, but they did not break the precision of their march to wipe it away. The astronaut corps and a handful of our spouses trailed the entourage. Between music selections the drummer maintained a solo staccato. The clop of hooves on the cobblestone mingled with the tapping of the women’s heels to compete with the drummer’s cadence. A symphony of other mournful sounds tugged at the heart: the choking sobs of women, the creak of the caisson, the groan of the leather tack, the jingle of a bridle.
