By the time AOPA's twelfth annual Fly-in and Open House officially began at 8:30 Saturday morning, scores of planes had already arrived at Frederick Municipal Airport (FDK).
The day started CAVU, with temperatures in the low 80s by 9 a.m.
Early arrivals headed almost immediately for the static displays on the AOPA ramp or for the safety seminars. By the time the Fly-in and Open House ends, hundreds will have attended the 17 different seminars being offered today on everything from "Hangar Talk" with Rod Machado to collision avoidance and spatial disorientation.
