Exactly -- it was done weeks ago -- and that's the point.
It would have just indicated a likely spot on the 8:11 arc given the two different speeds. So 450 knots would have put it further south.
Exactly -- and the only way to get to that new search area is to plug in the slower 400 knot speed for the last 5 hours.
It flew faster during the first two hours as the pilot was anxious to get out of that busy air corridor as quickly as possible before he was spotted, flying as low as 12,000ft to avoid planes flying at the upper altitudes.
Okay, that makes sense.
Where the news program was misleading was that it implied that the plane flew faster the entire time. Obviously, it couldn’t have, or it would have ended up farther south than the original search area, not farther north. (But I only watched the first minute; maybe they cleared it up later in the report?)
