demachina writes: Robert Boisjoly dies at 73. Boisjoly, Allan J. McDonald and three others argued through the night to stop the Challenger launch but Joseph Kilminster, their boss at Morton Thiokol overruled them and NASA managers didn't listen to the engineers. Both Boisjoly and McDonald were blackballed for speaking out. NASA's mismanagement "is not going to stop until somebody gets sent to hard rock hotel," Boisjoly said. "I don't care how many commissions you have. These guys have a way of numbing their brains. They have destroyed $5 billion worth of hardware and 14 lives because of their nonsense."
