This is a misleading article. The cause of the Malaysian crash is known and that cause is not accurately reported by this piece. Moreover, there is an assumption in this article and widely believed elsewhere that the cause of the Ethiopian airliner is likely identical. That is not true, rather that is just one of any number of possible causes. Lots of speculation, very few verified facts at this stage.
Great post.
Wasn’t there a lot of reports of visual smoke/fire on the second crash?
