Broken Altimeter, Ignored Warnings: Hearings Reveal What Went Wrong in DC Crash that Killed 67

The whole system is to blame IMHO. Every part of the system, the controllers, the pilots, the altimeters, etc were a giant cluster foxtrot.
The entire system needs an overhaul and oversight.

A lot of 'it wasn't me's' going on in this.

We can't undo what happened but we damn sure can keep it from happening again.

While I was active in Germany, there were 3 Secondary Cal Labs. One summer the other 2 labs had to shutter their Barometric sections and personnel were sent for retraining. They failed a test from the Army's Primary Standards Lab. I missed the check by parts per trillion. For that summer I was responsible for every transfer teams altimeter and pitot static test set in the European theater. I put in a lot of overtime. I don't know anything about the radar altimeter mentioned in this article, but I like the idea.
