You could almost say: "now what has that to do with the price of lawnmowers?".....
I thought that, so far, ATC was not really involved at all.
ATC wasn't directly involved but after the Cindacta I and Cindacta IV failures, the ATC go-slow, and endless delays and mayhem the JJ accident was the last straw. Someone had to go, and I suspect Pires was first in line.
