O'Keefe's teenage son, Kevin, was also among the four survivors. Both have broken bones and other unspecified injuries, said Glenn Mahone, former NASA spokesman, who spoke to the family.
Stevens was among five people who died when their bush plane crashed last night near a remote fishing village in southwestern Alaska, where they were headed for a fishing trip.
O'Keefe headed NASA during the shuttle Columbia disaster in February 2003. He resigned in 2005 to become chancellor of Louisiana State University, then joined European military contractor EADS in 2008.
