I caught a snippet of his comments, complaining about managing "thousands of flights" using "slips of paper".

It's been a few years, but I recall reading at least one article wherein was described how those slips of paper actually made a lot of sense. (It may have been one of the articles that made the rounds, describing the surprising endurance and resilience of paper-based work.)

The slips of paper supported both regular and immediate, ad hoc workflows as they were needed. Also, paper is immune to systems failures. Your electronic board goes down -- you still have all your flights at hand. Start spacing them and shoving incoming traffic into wider holding patterns.
