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.
