A former NASA spokesman says ex-NASA chief Sean O'Keefe survived the plane crash in Alaska that killed former Sen. Ted Stevens.
Glenn Mahone (Muh-HOHN') says O'Keefe's teenage son, Kevin, was also among the four survivors.
The plane crashed Monday night near a remote fishing village in Alaska, killing five.
The former spokesman for the space agency says he has talked to O'Keefe's family. They told him that O'Keefe and his son had some broken bones and other injuries.
