Roger Boisjoly was a booster rocket engineer at NASA contractor Morton Thiokol in Utah in January, 1986, when he and four colleagues became embroiled in the fatal decision to launch the Space Shuttle Challenger.
Boisjoly was also one of two confidential sources quoted by NPR three weeks later in the first detailed report about the Challenger launch decision, and the stiff resistance by Boisjoly and other Thiokol engineers.
The experience both haunted and inspired Boisjoly in the decades that followed. We learned this weekend from this story in The New York Times that Boisjoly died last month in Utah at age 73.
Bulky, bald and tall, Boisjoly was an imposing figure, especially when armed with data. He found disturbing the data he reviewed about the booster rockets that would lift Challenger into space. Six months before the Challenger explosion, he predicted "a catastrophe of the highest order" involving "loss of human life" in a memo to managers at Thiokol.
The problem, Boisjoly wrote, was the elastic seals at the joints of the multi-stage booster rockets. They tended to stiffen and unseal in cold weather and NASA's ambitious shuttle launch schedule included winter lift-offs with risky temperatures, even in Florida.
On January 27, 1986, the forecast for the next morning at the Kennedy Space Center included a launch-time temperature as low as 30 degrees Fahrenheit. NASA had never launched in temperatures that cold and Boisjoly and his four colleagues at Thiokol headquarters in Utah concluded it would be too dangerous too launch.
Three weeks later, he told NPR's Daniel Zwerdling in an unrecorded and confidential interview, "I fought like Hell to stop that launch. I'm so torn up inside I can hardly talk about it, even now." ...
