A small plane that took off from Teterboro Airport in New Jersey crashed in a residential neighborhood in Connecticut this morning, and two children on the ground and the pilot of the plane were missing and presumed dead, according to the authorities.

The plane, a multiengine turbo prop aircraft, crashed just north of Tweed New Haven Airport at 11:25 a.m. and caused devastating damage to two homes on Charter Oak Avenue in East Haven.

Doug Jackson, the East Haven fire chief, said that a mother was with her two children — a 1-year-old and a 13- year-old — in one of the homes at the time of the crash. She escaped, but the authorities feared that her children did not.

Gov. Dannel P. Malloy of Connecticut said that two bodies had been recovered but that there might still be more victims.

“There are reports that there are two children in the house,” he said. “There are reports that there are one to three people on the plane.”

Malloy said that the plane’s wings struck both houses but that the fuselage landed squarely on one home.

While investigators were trying to determine the cause of the crash, Malloy said that the pilot had aborted his first landing attempt and was circling back for a second try.

“It appears that there was a first approach,” he said. “For whatever reason that approach was not executed.”

The pilot circled for another approach, and that is when he crashed, he said.

The flight from Teterboro to Tweed normally takes less than 30 minutes, and it did not appear to deviate from its planned flight path as it approached the airport. While it was a rainy and windy morning, the airport was operating normally.
