Well, since you just wave your hands and say so, that must be right.
And, duh, it will be the GPS system that puts the aircraft where
they're supposed to be in the flow so how is that irrelevant genius?



GPS doesn't put the aircraft in the proper sequence and at the proper
spacing. I do, using a variety of techniques that any pilot who has
flown in controlled airspace can tell you about. GPS can help you
navigate to a particular location in space but does nothing to establish
and then maintain a desired spacing.
