> Everyone knew that crashing commercial aircraft could cause a great deal of destruction but somehow we could never prepare for such a scenario until it actually happened.
Interestingly and off topic, the same lock that is intended to prevent take over of a plane, was used by a pilot to crash the plane and kill all 150 people [1]:
> The crash was caused deliberately by the co-pilot, Andreas Lubitz, who had previously been treated for suicidal tendencies and declared "unfit to work" by his doctor. Lubitz kept this information from his employer and instead reported for duty. Shortly after reaching cruise altitude and while the captain was out of the cockpit, he locked the cockpit door and initiated a controlled descent that continued until the aircraft impacted a mountainside.
Are we not? Current protocols eliminate almost all chances of taking over a plane with box cutters. People now know what is up and will risk a laceration to take out some homeboys when they know it means certain death if they don't
