German Plane Crashes

How do they know he deliberately crashed versus had a seizure or passed out?

"Cockpit doors can be opened from the outside with a code, in line with regulations introduced after the Sept. 11, 2001 attacks in the United States, but the code can be overridden from inside the cockpit. Lufthansa's CEO said that either the pilot had entered the code incorrectly, or the co-pilot inside had overridden it."

The aircraft would no descend by itself even if the copilot encountered some sort of health distress. It would simply kept in straight and level flight.

They're saying his breathing was normal and steady (whatever that means). Also, he deliberately pulled some switch that made plane go into a nosedive, plus he wouldnt open cockpit door for the other pilot.

Add all those things together and it looks like it was deliberate

A trail of circumstantial evidence (and remember unlike what television dramas may lead one to believe, circumstantial doesn't mean unconvincing, or second rate).

On top of what Rafterman and Destillat posted, seemingly the pilot used the intercom with no answer, then the co-pilot locked him out of the cockpit (the French prosecutor is saying that the pilot entered the code and the co-pilot then blocked him from entering and there is a five minute reset before you can try to enter the code again) this I presume was all from analysis of the Cockpit Voice Recorder, the French prosecutor also said that the sound of the pilot banging on the cockpit door and calling through the door to the co-pilot and of passengers screaming could all be heard. That the co-pilot's breathing through all of this is normal (no signs of changed breathing due to a medical issue or hypoxia).

Further, if the co-pilot hadn't commanded the autopilot to begin a steady descent the aircraft would have continued to fly at altitude along the route programmed and beyond until the aircraft ran out of fuel.

As already mentioned by Skyrider I suppose that European airlines will immediately adopt a two people in the cockpit rule.
 
What does a "two person policy" mean? Now they'll need three pilots aboard a plane so that at any given time, there are two pilots in the cockpit? When one has to go to the washroom at least two remain in the cockpit?

The problem in this situation was that one pilot was able to lock the other pilot out of the cockpit.

It simply means that when one of the pilots needs to leave the cockpit that they are replace by a flight attendant.
 
When I first heard this this morning it was with a sense of utter disbelief. How the Hell do you become so screwed up that you murder 149 people including infants and secondary school students. It doesn't appear to have been political or religious but plain old homicidal/suicidal mania.

I hate to sound heartless but if the co-pilot was suicidal, and yes, he should have sought help first, and nothing was going to stop him from ending his life, there are other ways to do it that don't involve taking 149 innocent lives with you.
 
The doors will now have an override for the override.
I doubt it, the greater danger is still crazies attempting to break into the Cockpit and seize control of the aircraft.

Don't quote me, but I believe I heard this morning that there have only been seven pilot murder/suicide crashes in the past twenty years and that's everything from puddle jumpers to Airbuses and Boeings.

how many terrorist acts? just curious...wanna see them in comparasion...
 
I disagree...sort of....Carling's link shows a bunch of hijackings, but most did not involve fatalities. I completely agree with the locking of cockpit doors post 9/11 but I think we need to take the possibility of suicidal pilots much more seriously given this crash as well as Malaysian Airlines 370 which was almost certainly the same root cause. A solution needs to consider both scenarios and protect against both -- perhaps separate security codes from flight attendant and pilot/co-pilot that will override any door locks....

It's a tough balance though... the more people that have access into the cockpit, the more opportunity there is for someone to exploit that access... think about it, now flight attendants have codes to get into the cockpit... what about suicidal flight attendants? Or flight attendants placed under duress by a terrorist?
