yeah. there was an incident many years ago which was conducting what s called an overshoot procedure and the systems overrided it and it ended up flying into the trees. what i want to say before we go down this route of engineering malfunctions is that this aircraft would have been at 32,000 feet or thereabouts. if there s any sort of malfunction in the system the pilot and the crew has a long time to start putting on emergency codes on the transponders 7700 that s the international recognized emergency code. they have a lot of time to start talking to air traffic, put out a more serious mayday call. there are a lot of protocols that should have happened should there have been some sort of engineering problem that we re talking about. so the fact that that was not done, what does that tell you about the situation in the cockpit? we don t know at the moment. and this is what we need to be careful about sort of going down
