The point of this article is it DIRECTLY contradicts the other articles claims of 100 mph updrafts, violetn thunerstorms AND lightning in the area. Go to the link of the article and you will see a Brazlian who tracked lightning strikes that night and shows there were none in the area of the plane.
The only “claims” of 100 mph updrafts I’ve seen were simply assertions that updrafts of that speed have historically been detected in thunderstorms in the area where this plane was flying — not that updrafts of such great speed had actually been documented during THIS flight. “100 mph updrafts” were cited as a possible cause/factor in this disaster, not cited as events which had actually been documented as occurring while this particular flight passed through the area. That some random Brazilian wasn’t personally able to detect lightning strikes in a location far from any detection equipment is hardly evidence that was no lightning there.
