KENOSHA - A man and woman died early Sunday when their helicopter smashed right through a home, but somehow the family inside the house escaped without injury. A mother, father and three children were inside the two-story home when the chopper crashed into the roof at the back of the building. The aircraft went through the entire home, exiting out the front of the building on the first floor. Click on the link under related content to see scene video from Chopper 4. Noel and Carla Wilson escaped injury on one side of the home; their children escaped injury on the other side of building. The house appears to be a total loss and may have to be torn down. The wreckage of the helicopter came to rest across the street from the damaged home on the next-door neighbor's front lawn. Debris from the Wilson's home covered the front yard and the street. Noel Wilson told TMJ4's Jay Olstad that his family was sleeping when the helicopter smashed into the house. "I didn't know what hit us. I thought we got hit by lightning," Wilson said. The crash blew the frames off of their bedroom doors. "We definitely were being watched over today, there is no question in my mind about that," Wilson said. Wilson, his wife, and their children, Matthew, 9; Zak, 6; and Katelyn, 2, all left their bedrooms and then saw the huge hole in the home's roof. Wilson said the helicopter had entered their house, taking off the railing of the stairs leading downstairs and exiting through the front of the house. The helicopter narrowly missed all of their bedrooms. "How we all walked out without a scratch, I can't quite grasp it," Wilson said. Wilson and his wife handed their three kids to waiting neighbors at the bottom of the damaged stairway. Then the parents walked down the stairs and out of the building. The helicopter caught fire shortly after the crash. The Kenosha Fire Department used foam to put out the flames. The crash was reported just after 5:30 a.m. at 6934 97th Avenue. The helicopter, a Robinson R44 Raven II, is registered to Midwestern Air Services of Kenosha. The crash site is about a mile directly south of the Kenosha Municipal Airport where the helicopter was based. The airport's tower does not open until 7 a.m., so travel earlier than that is "at your own risk," said Corey Reed, operations supervisor at the airport. The helicopter didn't have a flight plan on file, Reed said. Ed Malinowski, an air safety inspector for the National Transportation Safety Board, said a preliminary report on the crash will take about a week to complete. Malinowski said he didn't think the helicopter had a black box, which could have recorded the aircraft's operating conditions at the time of the crash. TODAY'S TMJ4 meteorologist Michael Fish said it was foggy in the area at the time of the crash. The National Weather Service said that at 5 a.m., visibility at the Kenosha Airport was about half a mile. Visibility had improved to about three-quarters of a mile to a mile by 5:30 a.m., meteorologist Chris Franks said. Family members identified the victims as Joan Anzalone, 45, of Racine and Alan Sapko, 54, of Kenosha. Sapko was the owner of Sapko International, a clothing company in Sturtevant. A family friend described Anzalone and Sapko as "longtime friends." Autopsies are scheduled for Monday according to the Kenosha County Medical Examiner. A neighbor told 620 WTMJ that she was asleep and woke up to a “big bang.” She looked outside, saw flames and immediately called 911. Her son said he heard “sputtering” just before the bang. Gary Stielow, who lives about 100 yards from the crash site, said he woke up and heard the helicopter stuttering and sputtering before it crashed.

It was at full power, but it was sputtering real bad. Then you just heard a loud boom." Stielow said he ran outside and saw that the family had made it safely out of the house. The bodies of the two people killed in the crash were on the ground next to the helicopter's engine, which was on fire, Stielow said. (The Associated Press contributed to this report)
