Re: Lion Air 737MAX8 Crashed Jakarta to Pangkal Pinang

It is unfortunate, but in this case there was what appears to be a criminally negligent maintenance screwup which caused a airspeed indication failure, which set the stage for the AOA malfunction and it was all exacerbated by what appears to be poor airmanship on the part of the PF. I hate to say t...

Re: Boeing’s automatic trim for the 737 MAX was not disclosed to the Pilots

I am guessing that with all that was going on in the cockpit in those short minutes the pilots never imagined that this was creeping up on them until it was too late. In other words, it would seem to me that they may have never considered (or had time) going through the runaway trim procedure which...

Therefore it is feasible to pull up and fly over. As someone posted earlier, once there's an aircraft in front of you, you are (a) not necessarily able to see if it is at the end of the runway or in the middle (b) do not know what its intentions are, could have turned and try to take off and (c) do...
