On Wednesday morning, police said the pilot attempted to make a landing on one of the runways when the B-17 aircraft crashed. The pilot had reported a problem shortly after takeoff and tried to swing the plane around. Police said the plane was in the air for approximately 5 minutes.

During the landing attempt, officials said the plane hit a landing instrument station, veered to the right, crossed the runway, and then struck a de-icing facility.

TIMELINE: 7 killed during B-17 crash at Bradley

The NTSB released video on Thursday of the B-17 wreckage.

The B-17 bomber was manufactured in 1944 and was purchased by the Collings Foundation in 1986.

This particular aircraft has one prior accident and one prior incident on its record, the NTSB said.

The accident happened in 1986 in Pennsylvania where it overshot the runway.

In 1995, the landing gear failed in Nebraska.

Nationwide there have been 21 accidents involving WWII era bombers, 3 of which were B-17G's.

The NTSB is looking for the public to email information, videos and pictures from the crash or moments leading up to it. The files can be emailed to witness@ntsb.gov.

Airport operations

The airport was shut down on Wednesday morning. The Federal Aviation Administration put a ground stop on all flights to the airport. The airport reopened just before 2 p.m.

The airport has since resumed operations.

Health advisory

The town of Windsor issued a health advisory on Wednesday for a potential discharge of firefighting foam into the Farmington River. The foam originated from the plane crash fire at the airport.

The Department of Energy and Environmental Protection responded to the crash.

Water tested for toxic firefighting foam following plane crash Connecticut environmental officials are keeping an eye on several water bodies following firefighting efforts from a deadly vintage plane crash.

Over the weekend, a family in Windsor said they witnessed foam accumulating in a backyard brook that feeds the Farmington River. DEEP was contacted. It set up barriers to prevent the spread and tested it.

DEEP expects the results in a matter of days.

"Containment and cleanup of materials released into the environment as a result of the Oct. 2 plane crash at Bradley continue," DEEP posted to social media. "We're monitoring Rainbow Brook, Watts Pond, Farmington River for accumulations of firefighting foam. If you see foam, report it to DEEP at 860-424-3338."
