BOSTON (WPRI) — An investigation is underway after a forklift operator was killed at Logan International Airport Tuesday afternoon, according to Massachusetts State Police.

Police said a 51-year-old man attempted to drive the forklift through a lower bag service entrance outside Terminal C when the backrest extension collided with a beam.

The forklift overturned on top of him, according to police.

Police said several workers rushed over and used an aircraft tow bar to lift the forklift up enough to pull the man out from underneath.

The man was rushed to Boston Medical Center where he was later pronounced dead.

Police said the man works for a sub-contractor with JetBlue.
