The Webb was behind schedule and over budget because the specs kept being changed. Once finally set it went reasonably quick
Sounds like the same insanity that went on with building some nuclear power plants .While under construction they kept on changing the blueprints! Someone here mentioned the real purpose of NASA nowadays is to pump money into the Districts of influential Congressmen. Seeing as how the Federal Government has become little better than a criminal syndicate with its grubby hands in everyone’s pocket I find that easy to believe.
