Dick - know the difference!
Dick. there is
1. Flight Planning and
2. Clearance.
You can Flight Plan all you like but if the weather, traffic, airspace or any one of dozens of variables are changed, so will your clearance.
So what if the system were changed to be able to file a PLAN over or through Willy? When you get close to mil airspace, civil ATC STILL have to ask for clearance and it would be granted or denied depending on the circumstances at the time.
You are asking for an amendment to a system that WORKS already.
Most of us who KNOW what goes on are shaking our collective heads!
Pick another cause will you!
