It would depend on how close together any two planes were flying. There were thunderstorms and I’m still leaning towards the plane being hit by lightning. Could have messed up some of the electronics and the pilot could only do so much after that. Nature does freaky stuff like that. And it would affect one plane and not another that was in the same general area.
All we can do is wait until they find the crash and study everything. And it sounds like they may have found the crash site.
Airbus is complete fly by wire, so a fried craft would have nothing to do but crash. No way to physically wrestle it down.
