Searchers battling treacherous swamps Tuesday could not find survivors or bodies near the wreckage of an Air Force cargo plane that crashed in Florida with eight people on board, officials said. The C-141B Starlifter crashed three miles north of Hurlburt Field Monday night while coming in for a landing, Air Force officials said. The plane was from Norton Air Force Base in Southern California. The fate of the eight people on the aircraft - seven crew members and a retired military passenger who boarded the plane during a refueling stop in Colorado Springs, Colo. - remained unknown, officials said.
