Sometime in the 80s, the powers that be decided to get rid of us old Vietnam Era people. We weren't spiffy enough. When given a task, we got the job done and then goofed off while the younger ones worked to get theirs done. We weren't exactly parade ready material and never were. We came from the time when you got the job done and no one cared how. The last 8 years of my time was just plain miserable. From what I gather, there was a time in the oughts when the powers that be figured out the mistake they made and there are a few people hidden like we used to be but called on when the time is needed. The F-15 is of that time period. And it appears that the F-15EX is just a continuation of that old F-15A.
