At least seven passengers are presumed dead after a vintage World War II-era B17 bomber that came to the Martha’s Vineyard Airport two weeks ago as part of a traveling exhibit crashed in Hartford, Conn., Wednesday.

Connecticut state police officials said in a press release Thursday that there were 13 passengers on board during the crash, three of them crew members. One passenger was confirmed dead, while four others were announced to be “presumed deceased.” Both the plane’s pilot and co-pilot were presumed dead as well. The five other passengers and on-flight engineer were injured in the crash, as well as one airport employee.

The Federal Aviation Administration confirmed that the plane crashed at approximately 10 a.m. Wednesday while attempting to land at Bradley International Airport. The airport said it was closed while an active fire and rescue team were at the scene, and later reopened.

According to a spokesman for the FAA, the National Transportation Safety Board is conducting an investigation into the crash. A list of the passengers provided by the Connecticut State Police name two as Massachusetts residents. David Broderick, 56, of West Springfield was confirmed dead. Andy Barrett, 36, of South Hadley was injured.

The plane was one of five fully-restored World War II-era planes that make up the educational nonprofit Collings Foundation’s Wings of Freedom touring fleet. Four of the five planes, including the B17, were on the Vineyard for three days in mid-September. As part of the living history exhibit, patrons could explore the inside of the planes, and for $450 take 30-minute flights. The organization also offers people the opportunity to fly the planes, starting at $2,200 for 30-minute sessions.

The B17 Flying Fortress that crashed on Wednesday dates to 1945, when it served as part of the Air/Sea 1st Rescue Squadron and later in the Military Air Transfer Service shortly after the war. In the 1950s, it was subjected to nuclear explosions, but was later restored and worked for 20 years dropping water instead of bombs on borate forest fires. In 1986, it was sold to the Collings Foundation and fully restored to its original wartime configuration.

According to information the Collings Foundation provides during its living history tour, the B17 had conducted over 2,700 tour stops since it became part of the organization’s fleet.
