Investigators hampered in black box search

Military planes located new debris from Air France Flight 447 while investigators focused on a nightmarish ordeal in which the jetliner broke up over the Atlantic as it flew through a violent storm.

Heavy weather delayed until next week the arrival of deep-water submersibles considered key to finding the black box voice and data recorders that will help answer the question of what happened to the airliner, which disappeared on Sunday with 228 people on board.
