A 23-foot (seven-meter) chunk of plane and a 12-mile-long (20-kilometer-long) oil slick were found early Wednesday, Brazilian air force spokesman Col. Jorge Amaral said. Rescuers have still found no signs of life.
The new debris was discovered about 90 kilometers (55 miles) south where searchers a day earlier found an airplane seat, a fuel slick, an orange lifevest and pieces of white debris.
The location of the new debris is consistent with where experts say currents in that part of the Atlantic would push anything on the surface.
That's indicative that whatever broke off in flight contained fuel -- stabiliser or wing. The convective weather would play its part among previously mentioned factors in separating the impact points.
Unlike the 747 breakup off Taiwan, we do not have shore based radar tracks of the various trajectories.
