You’ll notice - everything the governments get involved with are inundated by lawyers, squeezing out the scientists and engineers who won’t put up with their political games. The ones that stay under the lawyers control ARE the B-Team!
I believe Challenger was a direct result of those political managers. RIP.
For the supposed repository of the best and brightest, NASA’s big shots participated in not one, but two Space Shuttle disasters.
The first was the 28 January 1986 “Challenger” disaster caused by burn-through of the O-ring seal on the SRB after NASA ordered a launch when the temperature was below safety norms.
The second was caused by a reformulation of the insulation on the Shuttle's main fuel tank to go “green.” Asbestos was removed from the formulation and the new insulation frequently failed on subsequent launches. A large chunk of this reformulated insulation foam broke-off and compromised the Shuttle's heat deflecting tiles in the port wing. When Shuttle “Columbia” returned from its mission on 1 February 2003, the damaged area burned-through. Shuttle “Columbia” broke-up over Texas on its way to land at Cape Canaveral.
Given the current crop of “leaders” at the highest levels of NASA, the American space program might as well turn out the lights and shut its doors. None of these over-paid losers have a clue as to where NASA’s going. NASA’s like the Titanic after it hit the iceberg — everyone knows it's sinking — but no one knows how long it can stay afloat.
