“We have discovered 10 thousand ways of how not to make a light bulb.” - Thomas Edison.................
NASA launched Challenger when it was cover in ice, the mid-level engineers (the ones that know what they are doing) were begging senior NASA folks to postpone the launch.
NASA made a big mistake in the 80s. It promoted it great engineers into management. They were great engineers but they were HORRIBLE managers. I know cause I was there.
