It could be months before a full investigation of Friday's propeller plane crash in East Haven, Conn., is completed. In the meantime, the identities of the victims have been officially confirmed as Bill Henningsgaard, 54, a former Microsoft VP; his 17-year-old son, Maxwell; and two children in the house the plane hit, Sade Brantley, 13, and Madisyn Mitchell, 1. The town held a vigil for the victims on Saturday, NBC New York reports.
Pilot Henningsgaard didn't declare an emergency prior to the crash, says a National Transportation Safety Board investigator; there is no evidence thus far that there was "anything wrong with the plane," he notes. It was Heningsgaard's first approach to Tweed-New Haven Airport, the investigator says, though other reports have described it as his second approach. Henningsgaard was a noted philanthropist, NBC adds; he was named as one of 2013's Superheroes for Washington Families by parenting organization ParentMap, the Daily Astorian reports. He had previously survived a 2009 plane accident. (Read more Connecticut stories.)
