EAST HAVEN, Conn. (WTNH)-- There's more information about the final moments before that plane crash in East Haven that killed four people. 
 
 The NTSB came out with its preliminary report Tuesday and there is at least one witness that says the plane was flying upside down before the crash. 
 
 We heard what neighbors saw on the ground August 9th. 
 
 "The plane was really low and they're never that close to the center of town," said Nikky Zuniga, East Haven. 
 
 "It was a boom and then I heard a couple of rescue trucks go by, and so I went outside and saw this big plume of smoke," said Carolyn Smith, a neighbor. 
 
 The NTSB preliminary report says at 11:19, two minutes before the crash, the pilot, Bill Henningsgaard had been instructed to land on runway 20. 
 
 Henningsgaard acknowledged the plane is referred to as 622. Its registration number in the audio between the plane and the tower. 
 
 "Are you going to be able to make visual contact with the airport?" said Air Traffic Controller. 
 
 "Are you talking to 622?" said the pilot. 
 
 "622, affirmative." 
 
 "622's made visual contact." 
 
 
 
 "Ok." 
 
 Seconds later, the tower called out the plane's number in a panic. 
 
 "622." 
 
 And then nothing. 
 
 The report says a student pilot driving on I-95. "saw the airplane was inverted and traveling at a high rate of speed, nose first, towards the ground in the vicinity of where (the airport) was located." 
 
 A witness who lived two doors down said he saw the plane descending right side down into the homes. 
 
 Also, they noted the weather at Tweed, five minutes after the crash, which had wind from 170 degrees at 12 knots, gusting to 19 knots, visibility 9 miles, and overcast ceiling at 900 feet. 
 
 EAST HAVEN, Conn. (WTNH) -- A preliminary report on the fatal plane crash in East Haven describes the aircraft as being "inverted" and at a high rate of speed before the crash. 
 
 The National Transportation Safety Board issued a preliminary report Tuesday morning, describing radio traffic, the weather and flight conditions leading up to the crash. 
 
 A portion of the report cites the observations of a student pilot who was on I-95. "...he looked to his right while traveling east bound and saw the airplane at the end of a right roll. The airplane was inverted and traveling at a high rate of speed, nose first, towards the ground in the vicinity of where HVN was located. He stated that he stopped at a local business and found out that the airplane had crashed." 
 
 HVN is the three letter airport code for Tweed-New Haven Airport.

 The August 9 crash killed 13-year-old Sade Brantley and 1-year-old Madisyn Mitchell of East Haven, as well as the pilot, Bill Henningsgaard, and his 17-year-old son, Maxwell. The plane went down into two homes on Charter Oak Ave., a short distance from the airport, at 11:21 a.m. 
 
 The plane had taken off from Teterboro airport in New Jersey. 
 
 The preliminary report describes radio conversations between the New Haven control tower and the pilot. The pilot had been instructed to land on runway 20. Less than two minutes before the crash, Henningsgaard acknowledged that he was preparing to land on runway 20, and told the tower he "is in visual contact now" with the airport. 
 
 "At 1120:55 the HVN air traffic controller made a truncated transmission with the call sign '622'," the NTSB report said. "No further communications were received from the accident airplane." 
 
 Much of the plane and the two homes were destroyed in the crash and fire. Funeral services for the East Haven victims were held last week. 
 
 The wind was gusting up to 19 knots, or about 22 miles per hour, and there were overcast clouds at 900 feet, the NTSB said. 
 
 Environmental cleanup continues at the crash site, and once that is completed the homes will be demolished.

 The National Transportation Safety Board has released its preliminary report on the airplane crash in East Haven on August 9 that killed four people and it includes information from a witness who said he saw the plane, inverted and traveling at a high rate of speed before the crash. 
 
 William Henningsgard, of Medina, Washington, was operating the airplane and his 17-year-old son, Maxwell, was a passenger onboard when the aircraft went down on Charter Oak Avenue at 11:21 a.m. on August 9 and struck two houses at 64 and 68 Charter Oak Avenue, according to officials. 
 
 Sade Brantley,13, and her 1-year-old sister, Madisyn Mitchell, were in one of houses that was struck. All four were killed. 
 
 A student pilot who was traveling on Interstate 95 at exit 51 right before the crash told the NTSB he looked to his right and saw the airplane at the “end of a right roll.” It was “inverted and traveling at a high rate of speed, nose-first” toward the ground in the vicinity of Tweed-New Haven airport. 
 
 When the witness stopped at a local business, he learned that it had crashed. 
 
 A witness who lives two houses away from the crash scene told NTSB he was in his living room and saw the plane descending at a 90-degree angle, right-side down, into the houses. 
 
 The airplane Henningsgard was operating had left Teeterboard Airport in New Jersey around 10:49 a.m. on the day of the crash. Two minutes before the crash, the pilot told air traffic control that could see the airport. 
 
 The last radar target was at 11:20 a.m., according to the NTSB. 
 
 At that point, it was .7 miles north of the runway the plane was scheduled to land at and it was traveling at an altitude of 800 feet, according to the report. 
 
 When investigators arrived at the crash scene, they would find the front half of the plane, including the cockpit, left engine and front two-thirds of the fuselage in the basement, according to the NTSB. 
 
 The right wing struck another house and the right engine and propeller struck the ground between the two houses. 
 
 Fire consumed most of the wreckage. 
 
 The NTSB also noted the wind as of 11:26 a.m. as 12 knots, gusting to 19 knots, along with a visibility of nine miles and an overcast ceiling at 900 feet.

– Before crashing into a home in East Haven, Conn., the aircraft in the fatal crash was upside-down in what sounds like a nightmare scenario. According to a preliminary NTSB report, a witness "saw the airplane at the end of a right roll. The airplane was inverted and traveling at a high rate of speed, nose first, towards the ground" in the vicinity of the Tweed-New Haven Airport, where pilot Bill Henningsgaard was supposed to land. The former Microsoft exec, his 17-year-old son, and two children on the ground were killed. Another witness, who lives two houses from the crash site, saw the plane coming down at a 90-degree angle, NBC Connecticut reports. Less than two minutes before the plane went down, Henningsgaard told the control tower he was "in visual contact" with the airport and preparing to land, WTNH reports. A few seconds before the crash, the air traffic controller made a brief transmission, according to the report, but "no further communications were received from the accident airplane." The report also states that at the time of the accident the wind was gusting up to 22mph, and visibility was at 9 miles with overcast clouds at 900 feet.
