At least two people are dead with multiple others injured after a World War II-era B-17 bomber crashed at Bradley International Airport just outside of Hartford, Connecticut at 10 a.m. on Wednesday.

The bomber reportedly burst into flames after colliding with a building during an attempted landing. The plume of smoke is reportedly visible from miles around, with multiple accounts of the incident reaching social media within minutes of the crash.

Thus far, officials have not provided word on the total number of deaths, but multiple local outlets are already reporting that at least two people were ruled dead at the scene with at least six more hospitalized following the crash. It is not currently known if all of those involved were on board the aircraft or if any of the injured or killed may have been inside the structure the B-17 reportedly collided with.

“He was treetop level when I saw him,” Laura Nolan, who witnessed the crash, told the press. “And one of the engines wasn’t spinning.” Nolan, who previously worked as a paramedic, sped the airport to offer her assistance but was turned away.
