I agree entirely with ckings comments above,
It is time now to ensure that the flight deck becomes some kind of secure enviroment with the best planners in the aviation business finding a way that is ameanable and secure.
The BA 747 was seconds from certain disaster
and with 4 large airliners taken within minutes of each other, no-one is safe any more.
While we thought air-rage was almost unthinkable 10 years ago, now we are seeing things very differently.
Now that terrorists or anyone with cruel streak knows that these acts are certain to succeed,short of bodysearching all passengers,and blacklisting those from certain countries, this type of sabotage is almost certain to re-occur.
Its time to open our eyes to this new type of threat and get on top of it ASAP.
