Take-off. six minutes, in fact, after it took off, killing all 157 people on board. cnns richard quest is with us now from amsterdam. richard, what specific similarities have been identified? >> reporter: they didnt actually reveal what those similarities are, but its sufficient to say even the mere fact that the ethiopian transport minister said there were certain similarities between lyon air and ethiopian air, that in itself is of course a major development. experts point to the profile of th...

For us. and richard, youre the one who did the interview with the ceo of the airline. and the fact that he told you the pilots told air traffic control they were having flight control problems before the crash, what did that tell you? >> reporter: it tells me that there are too many similarities between what happened with the ethiopian plane and whats happened with lion air back in october. that plane, too, had flight control problems that eventually led the plane to crash very violently. rememb...

Thirdly, you get the good night, malaysia 370. and that all happens at around 1:18 1:19 1:20. and at 1:21 the plane makes this u-turn. and as it makes the u-turn it flies back over malaysia and during that particular flight nobody notices. the radar doesnt notice at all. and what the intelligence assessment is saying is that all these events that move this flight and then crucially, as it goes over out of here this turn all of which is monitored by primary radar, not secondary radar, these vario...

From descending it into the ground, making sure that nobody would see him. >> according to the report, the selected alty due decreased to 100 feet for three seconds and then increased to the maximum value of 49,000 feet. less than two minutes later, the selected altitude was 100 feet until it stabilized at 25,000 feet. the flight never left its scheduled path, so air traffic control didnt notice the altitude changes. >> the less the plane is equipped to stream the data and they decide to stream ...

Descent on the flight that preceded the flight. that indicates or strongly suggests that this is so important that they put this into the interim report that it appears to them that he did in fact rehearse all this. its interesting to point out that while the co-pilot changed the selected altitude of the autopilot several times, at no point did that influence the trajectory of the plane. it was supposed to be going down at that point in time. it did. they believe that because trajectory of the p...

Autopilot to 100 feet before leveling off again. >> he certainly was exploring the aircraft and its ability to go up or down and not stop him from descending it into the ground making sure nobody would see him. >> reporter: according to the new report the selected altitude decreased to 100 feet for three seconds. then increased to the maximum value of 49,000 feet less than two minutes later, the selected altitude was 100 feet until it stabilized at 25,000 feet. the flight never left its schedule...

He didnt notice the plane go down in any way. it wasnt noticeable in terms of altitude changes. i guess my question to you is if someones in there setting it from 100 feet to 49,000 feet back to 100 feet that doesnt register anywhere? with anybody? >> the plane was already in a cleared descent from about 39,000 feet to 21,000 feet. and so for him to spin the knob below the assigned altitude of 21,000 feet wouldnt change what the plane would do. if hed gotten to 21,000 feet and hadnt changed it w...

For three seconds. then increased to the maximum value of 49,000 feet. less than two minutes later, the selected altitude was 100 feet. until it stabilized at 25,000 feet. the flight never left its scheduled path so air traffic control didnt notice the altitude changes. >> unless the plane is equipped to stream the data and they decide to stream the data of the aircraft performance from the flight and someones monitoring it they wouldnt have noticed. it was clear the pilot didnt notice for anoth...

Stabilized at 25,000 feet. the flight never left its scheduled path so air traffic control didnt notice the altitude changes. >> unless the plane is equipped to stream the data and they decide to stream the data of the aircraft performance from the flight and someones monitoring it they wouldnt have noticed. and it was clear that the pilot didnt notice for another reason the front lab was inoperative. >> reporter: it appears it was a dry run for what he would do later that same morning on board ...
