Thick black smoke filled the air as a World War II bomber went down in flames Wednesday morning in Connecticut. The vintage B-17 crashed at Bradley Airport outside Hartford. There were 13 passengers on board Wednesday when the plane ran into trouble shortly after takeoff. Eyewitnesses say the plane was flying very low as it circled back around the airport. They say one of the engines appeared to have stalled. The plane landed hard, crashing into a de-icing tank.
