Four Bodies Pulled From Small Plane Crash Wreckage in East Haven, Conn.

Aug. 10, 2013— -- Four bodies have been recovered from a crash site in a residential neighborhood in East Haven, Conn., where a small plane nosedived into two homes, a fire official said.

Among those dead in Friday's crash are believed to be the plane's pilot, former Microsoft executive Bill Henningsgaard of Washington, and his 17-year-old son, Maxwell, who were onboard the aircraft and two children, ages one and 13, inside one of the houses -- who have been reported missing since the accident occurred.

The victims' names were not immediately released.

Their bodies were sent to the Connecticut medical examiner's office. They are believed to be the only fatalities, while initial reports indicated as many as six may have died in the crash, Anthony Moscato, deputy chief of the East Haven Fire Department said.

While the cause of the accident remains unclear, the National Transportation Safety Board and the Federal Aviation Administration is on the scene in East Haven, Conn., investigating the crash.

The 10-seater propeller plane plummeted from the sky and burst into flames when it collided into two homes less than a mile before it was due to touch down on the runway at Tweed New Haven Airport at approximately 11:25 a.m. Friday morning.

One of the plane's wings sliced through an upstairs bedroom of a home where neighbors said the infant and the teenager may have been.

"We saw it hit and one wing went through one house. The wing on the left side of the plane had landed through the bedroom where two children were," said neighbor Dennis Karjanis.

The children's mother reportedly could be heard screaming on the home's front lawn after the impact occurred, neighbors said.

"As to where they were, [the mother] said upstairs," neighbor David Esposito told told ABC New York station WABC-TV, who went into the home to locate the children after the crash. "I flipped over the beds and flipped over the crib and looked in the closet, but I couldn't find anybody. There was nothing."

Henningsgaard's family learned he had been involved in the crash after they saw the plane's tail number, his brother, Blair Henningsbard, told the Associated Press. Henningsgaard was reportedly taking his son on an East Coast college tour.

Tweed's airport manager, Lori Hoffman-Soares, said the pilot had been in communication with air traffic control and hadn't issued any distress calls, according to The Associated Press.

"All we know is that it missed the approach and continued on. There were no distress calls as far as we know," she said.

This isn't the first time Henningsgaard was involved in a plane crash. In 2009, he and his mother had to be rescued from a Washington River after the plane he was piloting experienced engine trouble, the AP reported.

A vigil for the victims of the crash will be held at Margaret Tucker Park in East Haven, Conn., this evening.
