"Through the Airport Watch program, your folks at
airports have the ability to call about anything they see that is
untoward or unusual that might help us. There is no additional
emerging heightened awareness for the Memorial Day weekend I can
provide, other than this is a three-day period with many events.
Pilots should keep their eyes open for anything unusual."
