Bad decisions by the Pentagon

The engine problems with the F-35 bring to a head some of the bad decisions in the last few years by the Pentagon. Their deciding to go with only one engine supplier for the F-35 is one. What if the engine selected is a dud or has problems like the Pratt does now? It looks like they would have learned from the F-14 that came out with just the Pratt engine that partially crippled the plane. The D model Tomcat with GE engines took the F-14 airframe to its full capability. Having two engines mfg for a plane gives some redundancy and back up.

IMO other bad decisions go a long way back. The cancelling of the b-70, and not too long ago the selection of the F-22 over the F-23 that was faster and far more stealthy. Too damned much politics, and not enough science, logic, and common sense.
