As Brazilian authorities indicate the recently recovered debris is not from Air France AF-447, all forms of theories are popping up.
More preposterous theories abound that Air France AF447 collided with another aircraft, possibly a drug runner. At 35,000 fleet? Drug runners fly their aircraft low to avoid radar, not way up for all radars to see.
There is one theory that a meteor collided with the doomed jet. I would have dismissed it, but it is from the highly respected Discover magazine. The logic they use is possible; I am no way saying it is probable, but the article is worth reading at least from a mathematical perspective.
The one fact we know for a certainty is that the answers are buried along with the two black boxes on-board F-GZCP; the flight data recorder and the cockpit voice recorder, but finding them in the deep waters off the coast of Brazil will be a herculean task.
