My house is about ten to fifteen miles east of LAX. Just minutes ago, I saw something incredibly frightening in the skies: two aircraft flying closer to each other than I had ever before personally witnessed, other than fighters in formation.
I got up out of my chair to watch them. In order to pass the leading one, the aircraft that had been in the rear accelerated suddenly. From my vantage point, it appeared that, at the passing point, there were a mere thousand feet at most between wing tips.
Hopefully, there are some air controllers that will be receiving some remedial training immediately, assuming they keep their jobs at all.
