Six people were killed on Thursday when a sightseeing plane crashed in a mountainous area of southeast Alaska, officials said, leaving no survivors. The craft had been ferrying five cruise passengers from a Holland America Line ship stopping in the port town of Ketchikan, the officials said, adding that the pilot was among the dead. "Poor visibility and deteriorating weather hampered aerial search efforts for part of the afternoon," Reuters quoted the Alaska State Troopers as saying in a statement, adding that an emergency signal had been triggered shortly before noon. The U.S. Coast Guard found the wrecked plane and the victims after a search that also involved the U.S. Forest Service and other agencies, the troopers said. The National Transportation Safety Board said it was sending an investigation team that is expected to arrive in Alaska late on Friday.
