AP - Authorities are still looking into the incident early this morning at Denver National Airport. The entire building and surrounding land appeared to be barricaded off, allowing no one inside, and there was no contact from anyone inside for nearly three hours. At this time, there's no confirmed word on what caused the barrier, and nobody inside remembers anything happening before the barrier came down. Police are looking into possible mutant involvement.
