you make a good point, or could cable to uplocks been pulled by slicing action of winglet
this will be a case of a bullet hitting a bullet.
has Brazil released any ATC radar data yet? didn't someone say that the radar showed 1000' seperation?

harkens back to that film I mentioned, "the crowded sky".
somehow I have to think the legacy was on top to survive.
