The widow of the small-plane pilot killed in a collision with a helicopter over the Hudson off Manhattan has filed a wrongful-death lawsuit accusing the copter company of operating an aerial “bumper car.”

The Aug. 8 crash killed nine people aboard the two aircraft, including pilot Steven Altman, of Ambler, Pa.

The federal lawsuit filed this week in Philadelphia by Pamela Altman seeks more than $1.3 million in damages.

She sued tour company Liberty Helicopters, helicopter owner Meridian Consulting I Corp., manufacturer American Eurocopter and several of their insurers.
