if he doesn t want them to come in he or she puts it on deny. and then once it s on deny no one can get in this cockpit. that s right. reporter: and five minutes later, they can get it on deny but then no one is getting in here. he has to switch it every time he wants deny. reporter: every five minutes to deny. puts it on unlock it s obvious that will unlock the door and somebody could come? yes. reporter: and one interesting thing is this tv monitor. this is not an all american planes on some american planes but what are you seeing on this monitor? from this monitor, most of the systems have three cameras outside the door. and they can take look at multiple views of who s outside the door. reporter: so you can see who s out the door it would be a great thing to have on every plane. that s correct. so you ll also have this people right here to where they can physically see through who s out the door. reporter: these reinforced cockpit doors keep people safer
moments before that crash, of somebody pounding and pounding and pounding on that cockpit door trying to get back in. but it was unsuccessful. that cockpit door was impenetrable. post 9/11 safety standards, right? once that door locks, nobody is getting in. that new standard locked cockpit doors, bullet proof, force proof doors, that standard has been used on commercial aircraft since 9/11 has been used for good an for bad. on the jet blue it was a very good thing there. he was apparently fine when he first got into the cockpit. something went wrong when he was in there. the co-pilot noticed and was able to get him out long enough to lock him out.
investigators are searching through the wreckage. hey, amy. reporter: hi, brian. i just called germanwings to try to get confirmation about that axe report. they are not saying anything about it now, but, i mean, you can imagine the captain would not have been able to pound through that door with his fists. the cockpit doors have been significantly reinforced since 9/11. and, therefore, it would be logical. but what gives me grief is thinking about the passengers having to see a captain taking an axe to a cockpit door in the final moments of their flight. in the meantime, questions about how volatile or how calculated andreas lubitz might have been, being now connected to some new reports coming out that he that suggest he took intentionally took the cruising altitude from 38,000 feet to 100 feet as soon as the captain left the cockpit. that is not confirmed. and we have not they have not
for reference and for context here, this is the press release from the u.s. federal aviation administration that was released in january 2002. specifically january 11th, 2002. four months to the day after the attacks of 9/11. this was the press release in which the faa announced mandatory new standards for reinforced cockpit doors on all commercial aircraft flying in the united states with more than 20 seats onboard. the faa s new rule announced four months after 9/11 required new newly strengthened doors that, quote, resist intrusion by a person who attempts to enter using physical force. that new rule required cockpit doors to remain locked. it re required an internal locking device so that it can only be unlocked from inside the cockpit. which is an excellent improvement in the rules of what you are trying to prevent, a
installed for cockpit doors? the door might be locked for a variety of reasons. some captains might have it locked out of the normal position. you could have a system where it is part of the warning system. many more emergency warning systems you d want to have sent to the ground first before lock. yes, it could well be. it might be on certain aircrafts in the system. the second one, fingerprints. that s a lot of technology. these are planes which are flown by tens of thousands of different crews at different times. that s a lot of finger prints. once you ve done it you ve got to get the communications to get the result of the fingerprint. how is it going to keep the database of tens of thousands of staff going to be using it? eyes idea but not practical. there s your answer. second question from twitter.
