Federal investigators will try to determine whether an open door on a plane caused it to crash on a San Diego golf course, killing a mother and son and critically injuring three other family members.
The homemade plane went down Monday afternoon after the pilot reported an open door shortly after takeoff. The door was later found a mile away.
Tom Little, an air safety investigator with the National Transportation Safety Board, says Thursday that the wreckage will be examined later this month. Little says among other things, investigators determine why the door was open and whether it hit the plane's rear engine.
The crash killed Lori Crane of Scottsdale. Her 8-year-old son later died at a hospital. Two other children and her husband were critically injured.
