Fire and rescue personnel surround the site of the crash Up to six people are feared dead after a small plane crashed in the US and engulfed two houses in flames.
The multi-engine, propeller-driven plane struck the homes near Tweed New Haven Airport, in the town of East Haven, Connecticut, as it went in to land.
National Transportation Safety Board investigator Robert Gretz said there were casualty reports of two or three people in the plane and two or three on the ground.
The plane may have been carrying two passengers, officials said He said authorities were at the scene looking for victims.
Soon after the crash, officials had said at least three people were missing: the pilot and two children, aged one and 13, in one of the houses.
Governor Dannel Malloy later said the plane may also have been carrying two passengers but officials were still trying to verify whether that was true.
The plane was coming in to Tweed New Haven Airport East Haven fire chief Douglas Jackson said: "We haven't recovered anybody at this point, and we presume there is going to be a very bad outcome."
He added: "There was an intense fire. There's heavy damage to both structures that were affected on both sides, the motor vehicle and then the aircraft involved."
A neighbour, David Esposito, said he heard a loud noise and then a thump. "No engine noise, nothing. A woman was screaming her kids were in there," he said.
The retired teacher said he ran into the upstairs of the house, where the woman believed her children were, and started frantically searching but could not find them.
Firefighters said they are predicting a "bad outcome" He returned downstairs and kept looking but then had to drag the woman out when the flames became too strong.
Mr Gretz said: "The plane struck two houses. One of the houses was struck more severely and part of the plane is actually in the basement, and obviously some of the house is in the basement as well.
"The state police are working with the fire department to go through the house to look for victims.
"What I saw was that it (the plane) was inverted with the left wing in one house, the right wing in the other, and I would say probably about 50 to 60% of it was consumed by fire, mostly the forward portion, forward of the wings.
"I was able to identify the two wings and the tail from what I saw, and with the forward portion being more buried towards the basement of the house."
Mayor Joseph Maturo said the houses were still unstable and crews had not yet completed a full search.
The plane, a Rockwell International Turbo Commander 690B, flew out of Teterboro Airport in New Jersey and crashed at 11.25 am US time.
Tweed's airport manager, Lori Hoffman-Soares, said the pilot had been in communication with air traffic control and had not issued a distress call.
"All we know is that it missed the approach and continued on," she said.
East Haven, which has a population of 30,000, is 80 miles (130km) northeast of New York City, on Long Island Sound.
