> You were never allowed to fly your glider within 10 miles of controlled airport, and 2 or 5 miles of an uncontrolled airport. Ever.
The above is demonstrably false.
Our AMA field boundary is less than 500' from the end of the runway of an uncontrolled, International US Airport - not in line with approach/departure obviously, but perpendicular to the runway. It's been there for 20+ years. We see commercial flights daily, and from our flight stations can easily make out the tail numbers on aircraft landing and taking off.
Further, the same government entity that owns the airport leases the land the field is on to us.
There's zero chance the FAA isn't well aware of our site.
