Im right on the outskirts of controlled airspace. Westover Airforce Base in Chicopee, Ma.. My AirMap and B4UFLY app says 100' altitude. When i request LAANC with Aloft or any other it say's preflight check failed but when i go to another controlled zone in another town and request LAANC all goes great and LAANC is approved. Why does this happen? I'm thinking Westover airbase does not want me to fly in there zone at all. Thanks for any help.
