pararescuemen so that they could continue work on and monitor the medical conditions of the survivors. Due to the nature of the survivors' injuries, the cabin could not be pressurized and the aircrew flew at a lower altitude. All patients were delivered to awaiting EMS in Anchorage at Kulis Air National Guard Base. A spokesperson for the Alaska National Guard said that rescuers were giving medical aid to survivors of the crash, and that three survivors were being airlifted to Providence Alaska Medical Center in Anchorage. Upon examination of the wreckage it was discovered that the ELT antenna had separated from the ELT housing on impact, thus disabling the emergency signal. It was also later determined that a functional satellite telephone that could have been used to summon aid was on board, but it went unused for hours, because passengers did not know it was there. Passengers The aircraft was carrying eight passengers and one pilot. Four of the passengers and the pilot died and two more were badly injured, with the last two suffering only minor injuries. Among the five fatalities was Ted Stevens, who was a former U.S. Senator from Alaska. Also among the fatalities were a GCI executive and her 16-year-old daughter. Among the survivors were former NASA Administrator Sean O'Keefe and his 19-year-old son Kevin, both of whom sustained non-life-threatening injuries but were listed in critical and serious conditions respectively the night after the crash. The senior O'Keefe sustained leg and neck injuries, and several of his teeth were broken. Stevens and O'Keefe had been fishing together before, and had been planning a fishing trip to a site near Dillingham at the time of the crash. Stevens had survived a crash at Anchorage International Airport in 1978 that killed his first wife. Pilot Theron "Terry" Smith, who also died, had lost his son-in-law in another plane crash less than two weeks before. Also among the dead was one of Stevens's former staff members, Bill Phillips. His youngest son, Willy, was seriously injured, and had to spend the night at the crash site with his dead father along with Jim Morhard, who survived. Investigation The National Transportation Safety Board (NTSB) sent a team to the site of the accident to investigate the cause of the crash. The team returned an inconclusive report in May 2011. They speculated that the pilot, a recovered stroke victim, may have fallen
