Do we have evidence that one controller did all ground and air? The only evidence I've seen was the NY Times said that, according to a source, two controllers were working and two more were in the building.
In situations like this there is as lot of disinformation. The best thing to do is not add to it - a pile of bad information is not improved by piling more on. The best thing is to patiently find reliable info and stick to it.

No disagreement here
Why do you (or why does anyone) think that? My point in the GP was, I have yet to see evidence that there was only one controller, and I have seen evidence that there were two.
