I have a remote pilot certificate. I was 4.9 miles southwest of Talladega, AL airport (not around race time). Called the airport number and the manager there says no flying within 5 miles. Talladega is Class E, 700' floor. Am I missing something? On the 107 authorization site, Class E with a 700' floor is not even an option. Does this manager need to take a basic airman knowledge test like us commercial guys? There was also another Class E airport nearby but we did not bother with them. Not doing anything facy, aerial surveying just above treetops. <10 minute flight time. I own a crash reconstruction company and we use these for mapping roadways. Seems like at least once a week we are under final approach on a Class E airfield. Thank you for any input.
