Your Letters Helped Challenger Shuttle Engineer Shed 30 Years Of Guilt
When NPR reported Bob Ebeling's story on the 30th anniversary of the explosion of the space shuttle Challenger, hundreds of listeners and readers expressed distress and sympathy in letters and emails.
On Jan. 27, 1986, the former engineer for shuttle contractor Morton Thiokol had joined four colleagues in trying to keep Challenger grounded. They argued for hours that the launch the next morning would be the coldest ever. Freezing temperatures, their data showed, stiffened rubber O-rings that keep burning rocket fuel from leaking out of the joints in the shuttle's boosters.
Bob Ebeling, now 89, at his home in Brigham City, Utah.
But NASA officials rejected that data, and Thiokol executives overruled Ebeling and the other engineers.
"It's going to blow up," a distraught and defeated Ebeling told his wife, Darlene, when he arrived home that night.
And it did, 73 seconds after liftoff. Seven astronauts died. Cold weather and an O-ring failure were blamed, and Ebeling carried three decades of guilt.
"That was one of the mistakes God made," Ebeling, now 89, told me three weeks ago at his home in Brigham City, Utah. "He shouldn't have picked me for that job. But next time I talk to him, I'm gonna ask him, 'Why me? You picked a loser.' "
Jim Sides listened to the NPR story in his car in Jacksonville, N.C.
"When I heard he carried a burden of guilt for 30 years, it broke my heart," Sides, an engineer, says. "And I just sat there in the car in the parking lot and cried."
Like many engineers who responded to Ebeling's story, Sides knows what it's like to present data and face resistance. He's also certain about who bears responsibility for the decisions that result.
"He and his colleagues stated it very plainly. It was a dangerous day for the launch," Sides says. "But [Ebeling] was not the decision-maker. He did his job as an engineer. He should not have to carry any guilt."
Sides wrote Ebeling a letter that mentioned Roger Boisjoly, a former Thiokol colleague who died in 2012 and rallied the engineers opposing the Challenger launch. Boisjoly addressed his own depression and guilt by making the Challenger experience a case study in ethical decision-making.
Many of the engineers who also wrote Ebeling credited him and Boisjoly for engineering school discussions that focused on the Challenger decision.
Did The White House Force The Challenger Launch?
Many readers and listeners responded to our Challenger anniversary story by repeating claims that the White House, under President Ronald Reagan, pressured NASA to launch Challenger on Jan. 28, 1986.
The State of the Union address was scheduled the same day.
"It is the most vicious and distorted rumor I ever heard," said White House spokesman Larry Speakes, in disclosing the rumor publicly a month after the Challenger tragedy.
The Presidential Commission on the Space Shuttle Challenger Accident concluded "there was total lack of evidence that any outside pressure was ever exerted on those who made the decision to launch."
The commission also found no evidence of a planned satellite link to the space shuttle during the State of the Union speech.
Commission member and skeptic Richard Feynman, who issued a separate Challenger report, conducted his own "surreptitious" investigation. He said he found no evidence of any outside pressure.
"They had an absolutely unrealistic launch schedule," says James Oberg, who spent 22 years at Mission Control at the Johnson Space Center before becoming an outspoken critic of NASA's safety culture.
Oberg cites earlier launch delays, two upcoming launches with planetary probes dependent on precise planetary alignment, and competition from a military space program.
"Your efforts show that your care for people comes first for you," Sides wrote to Ebeling. "I agree with your friend Roger Boisjoly. You and he and your colleagues did all that you could do."
Sides describes himself as a religious man and says Ebeling was wrong about God.
"God didn't pick a loser," he says. "He picked Bob Ebeling."
Ebeling's eyesight is so poor he can't read the letters himself. So his daughter Kathy read them aloud, including the note from Sides.
"That's easy to say," Ebeling responded. "But after hearing that, I still have that guilt right here," he said pointing to his heart.
This was a week after the Challenger anniversary story, and Ebeling sat in a wheelchair at his kitchen table, wearing a flannel shirt and pajamas. Letters and printed emails were stacked in front of him. Kathy picked another letter from the pile and tried again.
"You presented the correct data and blew the whistle," another listener wrote. "You are not a loser. You are a challenger."
Again, Ebeling wasn't moved. So I asked him if there's something more he wanted to hear.
"You aren't NASA. You aren't Thiokol," he said. "I hadn't heard any of those people."
Kathy noted that neither Thiokol nor NASA had contacted her dad since deep depression prompted his retirement shortly after the Challenger disaster.
"He's never gotten confirmation that he did do his job and he was a good worker and he told the truth," Kathy said.
Thiokol has since been absorbed by another company. There isn't anyone there or at NASA today who was likely involved in the launch decision.
Statement From Kathy Ebeling
I just want to thank NPR listeners on behalf of my dad, Robert Ebeling. He has appreciated all the emails, letters and notes from all of you. He has had a turnaround in his feelings of guilt about the deaths of the Challenger astronauts. We, as his family, love all of you and are grateful that you have contacted us. I have read every one of your messages to my dad. He is letting go of the guilt that he has held for 30 years. It is a miracle from God and from all the people who have written to us. I thank all NPR listeners for this amazing gift. My dad does not have much time left and your words are easing his mind.
But some retired participants in that decision are still alive, including 78-year-old Allan McDonald, who was Ebeling's boss at the time and a leader of the effort to postpone the launch. He called Ebeling right away.
McDonald told Ebeling that his definition of a loser is "somebody that really doesn't do anything. But worse yet, they don't care. I said, 'You did something and you really cared. That's the definition of a winner.' "
McDonald also reminded Ebeling that he first raised the alarm by calling the Kennedy Space Center, where McDonald was Thiokol's launch representative. That call prompted the 11th-hour teleconference in which the engineers told NASA it was too risky to launch.
"If you hadn't have called me," McDonald told Ebeling, "they were in such a go mode, we'd have never even had a chance to try to stop it."
McDonald also responded to some NPR listeners who were not sympathetic to Ebeling and the other Thiokol engineers. They said the engineers should have done more, including last-ditch calls to NASA's launch director or even the White House.
"You just don't do that," McDonald said. "They'd probably send a van out with some white coats and picked you up. ... The launch director doesn't take those outside calls either."
Another key participant in the launch decision was Robert Lund, who was Thiokol's vice president for engineering at the time. He was one of the company executives who approved the Challenger launch despite objections from Ebeling, Boisjoly, McDonald and others.
Lund wouldn't agree to a recorded interview, saying, "I don't want to relive it." He was reassigned by Thiokol and so "shamed by the neighbors" that his family was forced to move, he said. "It was a bad dream."
But Lund said he phoned Ebeling and told him, "You did all that you could do."
A former NASA official involved in the Challenger launch also declined to be interviewed. George Hardy was a deputy director of engineering at the Marshall Spaceflight Center, which supervised Thiokol's production of the shuttle's booster rockets. He famously said he was "appalled" when Ebeling and the other engineers argued that Challenger shouldn't fly in temperatures so cold.
Hardy now says he's gone over that night many times.
George Hardy speaks during Challenger explosion hearings in Washington, D.C., on Feb. 26, 1986.
"I've concluded that's of no great value to me or anyone else," he said.
But he did see value in writing to Ebeling.
"You and your colleagues did everything that was expected of you," Hardy wrote. "The decision was a collective decision made by several NASA and Thiokol individuals. You should not torture yourself with any assumed blame."
Hardy closed with a promise to pray for Ebeling's physical and emotional health. "God bless you," he wrote.
The note from Hardy and the phone call from McDonald seemed to be a turning point. It was two weeks now after the Challenger story, and Kathy had been reading letter after letter every day. Sitting in his big easy chair in his living room, Ebeling's eyes and mood seemed brighter.
"I've seen a real change," his daughter explained. "He doesn't have a heavy heart like he did."
Statement From NASA Acting Press Secretary Stephanie L. Schierholz:
We know spaceflight always has been, and will be, risky. Every year, we in the NASA community, including civil servants and contractors, pause to reflect and honor those who gave their lives for the benefit of all humanity. We honor them not through bearing the burden of their loss but by constantly reminding each other to remain vigilant and to listen to those like Mr. Ebeling who have the courage to speak up, so that our astronauts can safely carry out their missions. NASA has changed in many ways as a result, including a more robust management process with more oversight, and more opportunities for independent assessments. A direct recommendation resulting from the Presidential Commission following Challenger was that NASA should establish a separate office to address safety that reports directly to the NASA Administrator. Today NASA not only has the Office of Safety and Mission Assurance but also has independent advisory boards to help ensure we minimize what spaceflight risks we can.
The crews of Challenger and Columbia embraced the risk in a shared pursuit of exploration and discovery. We honor them by making our dreams of a better tomorrow reality and taking advantage of the fruits of exploration to improve life for people everywhere. Mr. Ebeling is part of the NASA community. We encourage him to join us in honoring their sacrifice and recognizing the differences their lives made, especially in NASA's approach to safety. We would welcome him at any of our Day of Remembrance activities.
Ebeling then jumped in.
"I know that is the truth that my burden has been reduced," he said. "I can't say it's totally gone, but I can certainly say it's reduced."
The night before, NASA had sent a statement and Ebeling hadn't heard it yet. The statement was emailed by a spokeswoman for NASA Administrator Charlie Bolden, a former astronaut. He flew on the shuttle flight just before Challenger, and later led the effort to resume shuttle flights safely.
"We honor [the Challenger astronauts] not through bearing the burden of their loss, but by constantly reminding each other to remain vigilant," the statement read. "And to listen to those like Mr. Ebeling who have the courage to speak up so that our astronauts can safely carry out their missions."
After hearing that, Ebeling clapped long and hard, and shouted, "Bravo!"
"I've had that thought many, many times," he said.
Ebeling is now more buoyant than at any time I've seen or talked to him in the past 30 years. It's been a rough three decades, and it hasn't gotten any easier. He's near the end of his predicted life expectancy for prostate cancer and has hospice care at home. He said he'll pray for God's assessment once our interview ends.
I asked him one more question. "What would you like to say to all the people who have written you?"
"Thank you," he said. "You helped bring my worrisome mind to ease. You have to have an end to everything."
Ebeling then smiled, raised his hands above his head and clapped again. Kathy Ebeling called that a miracle.
