Germanwings flight 4U 9525

[cheap]

As details of this crash emerge, it does seem to be either a rouge pilot or co-pilot at the controls and deliberately crashing the plane. Curiously the names of the pilot and co-pilot have not been released, which may indicate something.

We sure live in a crazy mixed up world. If the crash turns out to be a religious act of terrorism (like 9/11), then what's next, what has the airline industry learnt since 9/11?

Surely Nuclear Power Plants would be high value targets. Do we need to have anti-aircraft guns stationed everywhere or remove humans completely from the controls of planes?

Condolences to those people who have lost loved ones.
