To a large degree, the engineers WERE the project managers in the 70s and if
you take the F100 engine as an example things really fell apart as the
durabilty and reliability specs were non-existant. Too much new technology and
mainoy just a performance (thrust) spec. A large part of the F-15/F-6 fleets
were grounded due to the stall stagnation issue.

Before that there was grievous trouble with compressor discs flying
apart into a bunch of pieces and trashing the rest of the engine. I
was in the control room for the first MEA of the F-15.
