This week, the Peter Greenberg Worldwide Radio Show reports on the new and fascinating developments in the search for Malaysia Air flight 370—one of aviation’s greatest mysteries—as part of a wing strongly believed to be from the ill-fated Boeing 777 washed up on Reunion Island. What will that barnacle-encrusted wing tell investigators that might finally lead them to the rest of the wreckage?

How will oceanographers and marine biologists figure into the investigation, and what can they learn from the marine growth on that six-foot piece of metal? Will we ever know what happened on the flight that went missing 17 months ago? It’s all part of a special edition of the Peter Greenberg Worldwide Radio Show dealing exclusively with airline safety.
