My first two requests via the online form in September were for a specific date and location, and were rejected because these were too early for Class C -- our local Air Force base. But then, one was requested in early December for the period Jan 1 to April 1 for max 80 feet, from 1.2 NM to 5 NM (outside that of course is okay anyway). Permission finally came back at the end of January, but included Jan 29 to July 30 - Great!
