Okay, this is going to shock some BUT, in this case, I'm going to agree with much of Speed's post.
This thread, however, talks about a special case. This has nothing to with the FAA(the AMA's primary sparring partner) nor the AMA. This is strictly a DOD vs Club issue. What must be remembered is the base commander has given the clubs access to a DOD facility AS A COURTESY, not because he had to. The same thing has been done for several decades at NAS Whidbey Island WA with one of the local flying clubs. The only requirement, that I know of anyway, was that a certain amount of members of the club had to be DOD employees. FAST FORWARD TO LAST OCTOBER:
Per the Whidbey Island Radio Control Society newsletter, the Touch-N-Go, the club's field marshall had talked to the base about using the auxiliary landing field, the clubs home for the previously mentioned several decades. The results were that the DoD said no flying on any base area, but the old CO gave the club a waiver to fly. Also looking at MWR having a flying program with the club teaching the flying.
Since then, the base has closed the gates to the field and the club is now working on finding a new location.
What must be remembered is that most bases are commanded by either a Captain(navy and coast guard), a colonel or a low level general(air force, marines, army). They are not going to risk their careers by butting heads with the Pentagon over a small group of people with toy airplanes that has used their base as a flying field in the past. Security is now the watchword and, with quads and planes now being equipped with onboard cameras that transmit an unregulated signal that can be picked up by anyone with the tech to do so, it just makes sense to close the gates to protect what's classified from being seen by the wrong people.
