For me, the really puzzling part of this accident is that the engines initially produced enough thrust to get safely airborne, and do so without any warning or caution indications, but then suddenly stopped producing enough thrust to stay airborne. That is one heck of a troubling failure mode for incorrectly loaded software. That such a failure mode was not identified and positively prevented as tdracer noted above is indeed very very disturbing. And if it is being covered up, would indeed seemingly be criminal. I'm not saying there is or has been a cover up, but everyone involved sure appear to be very tight lipped with the facts concerning this fatal accident. What assurance do the current and future operators of this aircraft have that the problem is fully understood and has been thoroughly designed out to prevent a recurrence?
