Well, don't look now, because that's exactly what's happened. And, by the
way, C is far ahead of Ada in the Air Traffic field, with or without the
FAA.

I generally agree. I didn't claim that Ada was the reason that AAS
crashed. I doubt that any language, however perfect, could have saved
AAS. It's a long and ugly story. But, fair or not, the FAA has in fact
turned away from Ada.
