With the flightline being active again, it is extremely important to stay out of any areas designated with yellow signs. Yes, those signs have been there for many years and we have been able to ignore them. There is now security monitoring the flightline and cameras will be installed soon. Referrals will be made to law enforcement for trespass violations. There are some barricades in place and those are occasionally moved. All unauthorized people to stay away from the flight line, alert hangar, DC hangar, Arch hangar and any other areas marked.
