Terrifying Moment When Helicopter Blades Collide at Pasadena Police Heliport

A security camera captured the terrifying moment when rotor blades of two Pasadena Police helicopters collided at a heliport in Altadena, California. Both helicopters were damaged and six people were injured.

The footage of the incident that occured on Nov. 17, 2012, was released by the National Transportation Safety Board (NTSB) in August 2016, but it only came to light in early March 2018 after a US media report.

In the footage, one helicopter is seen attempting to land on one side of the heliport while another is preparing for departure. However, the landing helicopter got too close and the aftermath of the collision was devastating.

The collision was blamed on rainy weather and the lack of communication between the pilots, reported Storyful. The landing pilot failed to seek clearance from the departing pilot who should have parked the helicopter inside a marked pad but did not do so due to drainage issues.

“At the time of the accident, there was no established monitored UNICOM frequency at the heliport, and there were no procedures to alert ground personnel that a helicopter was arriving to the heliport other than by ground personnel ‘hearing’ it approach,” the NTSB said, reported the news website.

Authorities said they have since implemented universal communications and radio procedures for helicopter arrivals and departures.
