It seems like yet another inability to settle on a sensible solution due to holding corporate constructs sacrosanct. Ma Bell "bought" some colors of light, making the FCC unwilling to tell them to hold off to avoid interfering with existing infrastructure, so it was left to the FAA to pick up the pieces. Then the mitigating actions of the FAA will be characterized as "incompetent government" when the real problem was corporate corruption at the FCC.

Interagency cooperation is a well documented issue in our current government. However, this discussion has clearly occurred for years if you look at the documentation. Simply, nothing was done to resolve the issue until the true effects came to bear. People realized there was an issue. Both sides saw the issue. Both sides issued documentation. Both sides did nothing until the issue actually happened. Then they freaked out. I blame the FAA for this one. They should have raised their concerns publicly much earlier. I have worked with the FAA a bit, I have not been impressed.

If only there was someone who Presided over all these agencies, and could fix this. /s

Of course in the real world, the utterly stupid decision to sell colors of radio waves instead of just regulating their use has this predictable result.

I just finished "Flying Blind", describing how the Boeing engineering and oversight culture was destroyed, and I know how. These agencies have been gutted and corrupted and are no longer there to regulate. They are there to facilitate shareholder value. They are supposed to protect the public good on our tax dime, but we are not the customers - the CEO and the nebulous shareholder is the customer.

The same reason they allowed Boeing MAX with the MCAS (May Crash Any Second) to fly.
