Forty-one bodies have been found in the Atlantic thus far, two on Saturday, 14 on Sunday, eight on Monday, and 17 on Tuesday, all confirmed to have been on Air France Flight 447, Brazilian officials said Wednesday.

French authorities are urging searchers to show “extreme prudence” before identifying wreckage found in the Atlantic as being from Air France Flight 447, after Brazilian workers incorrectly publicized they had found debris from the missing plane Thursday.

French investigators say they are not optimistic the black box recorders from Air France Flight 447, now buried deep in the icy waters of the Atlantic Ocean, may ever be found, BBC reports.

An Air France plane carrying 228 people vanished over the Atlantic Ocean after reporting a short circuit caused by a possible lightning strike, the BBC reports.

Since the last Index was published nearly six months ago, New York and London have lost fewer points than both Singapore and Hong Kong. Some Asian cities have taken a large hit, namely Tokyo, which fell from a seven ranking to a 15 and lost 31 points, the largest drop in the top 20. Some cities, like Boston, Dublin, Toronto and Guernsey, have even capitalized on the losses of others, rising in the rankings despite losing points.
