The wife of the small plane pilot who was killed when his plane and a sightseeing tour helicopter crashed above the Hudson River in August is now suing the helicopter tour company. The AP reports, Pamela Altman's lawsuit against tour company Liberty Helicopters and helicopter owner Meridian Consulting I alleges that they had a "horrid history of accidents;" manufacturer American Eurocopter is also named in the suit as failing "to equip the helicopter with sufficient safety equipment." Besides Altman's husband Steven, his brother and nephew were killed as were six Italian tourists in the chopper and chopper pilot.
