Being Asked to Soften the Urgency of the O-ring Problem

Texto en Español

My notebook entry on August 15, 1985, reads as follows: "An attempt to form the team (referring to the Solid Rocket Motor seal erosion team) was made on 19 July 1985. This attempt virtually failed and resulted in my writing memo 2870:FY86:073. This memo finally got some response and a team was formed officially. The first meeting was held on August 15, 1985 at 2:30 pm." The memo referred to is the one I read to the Presidential Commission on February 25, 1986, which was written to the vice president of engineering at Morton Thiokol on July 31, 1985. The memo ended by saying, "It is my honest and very real fear that if we do not take immediate action to dedicate a team to solve the problem, with the field joint having the number one priority, then we stand in jeopardy of losing a flight along with all the launch pad facilities."

During this July period, NASA headquarters in Washington D.C. asked Morton Thiokol to prepare a presentation on the problems with all the booster seals. The presentation was prepared by MSFC on August 19, 1985, with Morton Thiokol personnel in attendance.

Morton Thiokol was then asked by MSFC in September to send a representative to the SAE conference in October to discuss the seals and solicit help from the experts. I prepared and presented a six-page overview of the joints and the seal configuration to approximately 130 technical experts on October 7, 1985. However, I was given strict instructions, which came from NASA, not to express the critical urgency of fixing the joint but only to emphasize the joint improvement aspect during my presentation.

Discussion Question

NASA once again wanted the seal task force team to soften the urgency of the O-ring problem. If the word leaked that there existed a major malfunction in the solid rocket booster, Congress would likely lose even more faith in the Shuttle program. No cold weather launches were scheduled for the near future. Should Boisjoly continue to listen to NASA and play down the importance of the problem? Which of the following are good things to do in this situation?
