How long did it take the Air France flight(The one from Rio to Paris) to surface? Heck who knows if the oil slick has anything to do with the plane, could be unrelated(I know thats far fetched but who knows)
Not sure how long but I think they didn’t find the main wreck site for over a year, but they did find debris within days ( I think) after the crash. I also had the same question about the slick...you would think they could test to see if there is any aviation fuel within the slick.
