The plane, a Cirrus SR22, was approaching Hanscom Field near the Burlington Mall when the pilot reported engine trouble and it crashed into a heavily wooded area, near 155 Middlesex Turnpike. Firefighters responded to the scene.
The pilot and passenger aboard, a man and a woman, were shaken up, but not hurt.
Bradley Debski saw it all unfold.
"I was, just happened to turn around and look out my hotel room up on the hill right here. And the plane was kinda making a right turn and them dipped down about maybe 100 feet," he said.
The plane had a parachute attached to it, which helped gently guide that plane to the ground It landed in a swamp behind one of Burlington's water treatment plants. The water supply is not contaminated, officials said, and the plant was immediately shut down. All of Burlington's drinking water is now coming from its other treatment facility, which is large enough to service the whole town.
A group of electricians were working on a job nearby, who also rushed to help.
"There was like four of us going in. By the time we reached the plane the fire department had already got there," said John Ullom. "The two occupants had already been extracted. They were standing around."
The FAA and NTSB will investigate.
