!! History Commons Alert, Exciting News
Profile: Joseph Vickers
Joseph Vickers was a participant or observer in the following events:
Following a company-wide order instructing them to warn aircraft to secure their cockpits (see 9:21 a.m. September 11, 2001), flight dispatchers at United Airlines’ headquarters issue an alert to all their pilots, stating: “There may be terrorist acts in progress. Do not open cockpit doors. Secure the cockpit.” Furthermore, Joseph Vickers, the director of flight dispatch, initiates a procedure for “positive contact.” This means the dispatchers must make direct contact with each aircraft every 10 to 15 minutes and confirm that its cockpit is still secure.
