Bloomberg News reports that "French satellite scans provided fresh indications of objects adrift in part of the Indian Ocean that's being scoured for the missing Malaysian airliner, backing up Chinese evidence as more planes and ships join the hunt. ... The developments rekindled prospects for a breakthrough in the mystery of Malaysian Air (MAS) Flight 370 after radar and visual scans failed to find objects spotted in earlier images taken from space. Searchers, bolstered by a growing fleet of international vessels, also want to locate a wooden pallet seen from the air to check if it could have come from the jet's hold."
And if you have your own database of recent photos to trawl through, the article says "The Chinese photo, taken March 18, is focused 90 degrees east and almost 45 degrees south, versus almost 91 degrees east and 44 degrees south for similar items on a March 16 satellite image, putting the object 120 kilometers southwest of that sighting."
