These are supposedly the latest images of the search area taken Monday IIRC.

If he's down in one of the frames don't expect the aircraft to look like the aircraft in the example. Crash sites look different -- the wings may not be attached, it may be belly-up. I'm assuming these are infra-red images. The aircraft has fabric and metal, not sure how that looks on IR. It would be nice to see a Citabria Super D in the example image.
