Former head of the Delaware National Guard, Carol Timmons, recalled barricading herself inside the cockpit of Flight 23 on 9/11 after a flight attendant reported four unruly passengers. The plane was evacuated during a ground stop and the problematic passengers managed to escape but weapons and ties were found in their luggage, Timmons claimed.
OH they got away.
So easy to just disappear in the middle of an airport runway...
