(FOXNews.com) -- Authorities have recovered four bodies from the site of where a small plane crashed into two Connecticut homes, a fire department official said Saturday.
Anthony Moscato of the East Haven Fire Department said the bodies of two people from the plane and two people in one of the homes were recovered overnight. The deputy chief says authorities now believe those were the only victims.
Earlier Saturday, the brother of former Microsoft executive said the executive and his teenage son were among the dead.
Bill Henningsgaard, who was piloting the plane, and his teenage son, Maxwell, were traveling the East Coast to visit colleges, and Connecticut was part of the itinerary, said Blair Henningsgaard, the city attorney in Astoria, Ore. He said the family learned it was Bill Henningsgaard's plane through the tail number.
CTNow.com reports two children, ages 1 and 13, were believed to be in the home at the time of the crash. The children's mother was also reportedly in the home, but escaped.
The multi-engine, propeller-driven plane struck the small homes while trying to land in rainy weather at Tweed New Haven Airport. Firefighters found both homes engulfed in flames when they arrived. The aircraft's left wing lodged in one house and its right wing in the other.
The Federal Aviation Administration says the Rockwell International Turbo Commander 690B aircraft flew out of Teterboro Airport in New Jersey and crashed as it approached Tweed New Haven at 11:25 a.m. Friday.
Neighbor David Esposito said he heard a loud noise and then a thump. "No engine noise, nothing," he said.
He also said he heard a woman screaming that her children were inside the burning home. He said he ran into the upstairs of the house, where the woman believed her children were, but they could not find them. They returned downstairs to search, but he dragged the woman out when the flames became too strong.
Frank Diglio, 55, told the Hartford Courant that he was driving nearby and pulled over when he saw people screaming and crying. Diglio said he and another man tried digging through the room to find the children, but were forced to leave after 10 minutes when the fire at the house became intense.
"The plane was burning slow and then it started really burning," he told the newspaper. "The fire engines arrived in like 10 minutes. They came real quick and they told us all to move. The house got really out of control."
Tweed's airport manager, Lori Hoffman-Soares, said the pilot had been in communication with air traffic control and did not issue any distress calls.
"All we know is that it missed the approach and continued on. There were no distress calls as far as we know," she said.
Another neighbor, Pablo Arenas, said he and his neighbors live in fear of the planes. He said some pilots appear to be novices in training, while others said planes often fly low and larger aircraft have begun using the airport in recent years.
Maturo, the mayor, said a priest was with the woman whose children were feared dead, and he offered sympathy to the family. Neighbors said the woman moved into the neighborhood recently.
"It's total devastation in the back of the home," he said.
It wasn't Henningsgaard's first crash. In April 2009, Henningsgaard was flying a small plane from Astoria to Seattle when the engine quit and he tried to glide back to the airport.
As he wrote 10 days later on a blog post, the plane crashed into the Columbia River after a harrowing five-minute descent. He and his mother, a former Astoria mayor, climbed out on a wing and were rescued.
Henningsgaard spent 14 years at Microsoft in various marketing and sales positions, according to his biography on Social Venture Partners website. The foundation extended its condolences to his wife and two daughters Saturday.
"There are hundreds of people that have a story about Bill -- when he went the extra mile, when he knew just the right thing to say, how he would never give up. He was truly all-in for this community, heart, mind and soul," the foundation posted Friday on its website.
Henningsgaard was a longtime board member at Youth Eastside Services, a Bellevue, Wash.-based agency that provides counseling and substance-abuse treatment, and led the organization's $10.7 million fundraising campaign for its new headquarters, which opened in 2008.
A vigil for the victims of the crash is planned for Saturday night at Margaret Tucker Park.
