Pasadena Police Department (PD) helicopter struck a stationary Pasadena PD helicopter while maneuvering to park at the Pasadena Police Benedict Heliport in Altadena, California
The air support Lieutenant (Lt.) was interviewed on November 18, 2012. He had observed that throughout the day prior to the accident, the weather had been spotty; clear one moment, cloudy and overcast the next. As N911FA took off, he observed from his office marginal weather conditions. A couple of minutes later, he looked out his window, and noted that the weather was closing in, and that N96BM was on Pad 1 preparing to take off. He walked out of his office toward N96BM, with the intent of telling the flight crew to stand down. He stated that he had been standing by the left door on the outside of N96BM. He observed N911FA returning to base, and thought that was a good thing. He recalled hearing a loud bang, getting knocked to the ground, and then running away from N96BM.
