May I remind you all of this incident! This guy stole a police car in the City, drove it to the airport! Broke through a fence and , well you can see the rest in the video!
BTW Are crew trained for situations like this? In the video you can see the cabin crew of the plane parked looking out and watching whats going on!They then shut the doors and push away the steps locking themselves in the plane! Is this standard security procedure? Or was it just a decision taken by the crew at that moment?
AFAIK the plane was half boarded!
