No worries
I would rather people ask and learn rather than listen blindly to the media lol
There are many reasons the non-sleeping pilot might not have been reacting, such as he was warned ahead of time by air traffic control (which the sleeping pilot would not know), and no, we never ignore a warning, but there are times when we pass close together, say in the U.S. with high congestion, and we can see the other plane and do not consider it a threat.
Nope, he would have been following a command from the TCAS, if that is what it was... Ie, you would get a "TRAFFIC TRAFFIC DESCEND DESCEND DESCEND" and on our planes there is a Vertical Speed Indicator that tells us how much to climb or descend depending on certain factors (IE Closure rates, etc..) so he dove (it is quite aggressive), then protocol dictates we return to our last assigned (So the climb)altitude asap and inform ATC what we did. or the other pilot started yelling at him " WHAT the hell are you doing???" lol
Remember when jets are converging, we are each doing 800+kms an hour, sometimes there is only seconds to react, not to say this guy didn;t goof up, but most would rather we err on the side of caution :lmao:
