Roger Boisjoly had over a quarter-century's experience in the aerospace industry in 1985 when he became involved in an improvement effort on the O-rings which connect segments of Morton Thiokol's Solid Rocket Booster, used to bring the Space Shuttle into orbit. Boisjoly has spent his entire career making well-informed decisions based on his understanding of and belief in a professional engineer's rights and responsibilities. For his honesty and integrity leading up to and directly following the shuttle disaster, Roger Boisjoly was awarded the Prize for Scientific Freedom and Responsibility by the American Association for the Advancement of Science.

Mr. Boisjoly died of cancer in St. George, Utah on Jan. 6, 2012.  He spent his final years offering workshops and lectures on changing workplace ethics for numerous universities and civic groups.

The Challenger Disaster

Space Shuttle Challenger taking off

January 28, 1986. Two video clips of the Challenger Explosion from CNN: "Reagan honors shuttle crew (1986)" and "NASA remembers Challenger".

In January of 1987, nearly a full year after the Challenger exploded, Roger Boisjoly spoke at MIT about his attempts to avert the disaster during the year preceding the Challenger launch. According to the Report of the Presidential Commission on the Space Shuttle Challenger Accident, "evidence pointed to the right solid rocket booster as the source of the accident." In 1985 Boisjoly began work to improve the O-ring seals which connect segments of Morton Thiokol's solid rocket booster. Boisjoly was frustrated with the slow progress and the lack of management attention to the seal task force. He spoke about the events leading up to the disaster in this address.

Boisjoly's discussion of the Challenger Disaster is separated into seven sections. Each section is then followed by some possible responses.

You may want to consult some of it in deciding what you would have done in Roger Boisjoly's place at each stage of the story.
