Regarding knee-jerk reactions, I read this yesterday in the German newspaper Welt Kompakt.
The German version can be found
here.
And here's my translation:
The investigation into the plane crash constantly bring new details to light. The co-pilot was apparently seriously mentally disturbed. His stealth was so great that it must have been obvious. Talk show hosts wonder how many dangerous Pilots are still flying and how they can be recognized. An incomprehensible announcement during the flight is, however, no clue.
Almost all airlines have now introduced the two-person rule. There must always be two people in the cockpit, and one of them should know how to fly the airplane. Also, two stewardesses should be quite able, according to experts, to land the airplane. Whoever can maneuver a crowded trolley safely through narrow isles, probably can also control an aircraft.
The only question is whether two people are really enough. A psychiatrist, a pastor and a doctor should definitely be present in the cockpit, at best, a medical practitioner, a Feng Shui master and a journalist. Add to that a mediator so there are no arguments.
