The staff at a TV news station in the US city of Seattle had to cover their colleagues’ deaths minutes after the helicopter the two men were in plunged off their building into the street below.
The chopper was taking off from a helipad on KOMO-TV’s roof when it went down at a busy downtown intersection and hit three vehicles, starting them on fire and spewing burning fuel down the street.
The two people on board died in the crash while a man in a car was badly injured.
KOMO identified the pilot as Gary Pfitzner, of Issaquah. The other man killed in the crash was Bill Strothman, a former longtime KOMO photographer. Both men were working for Cahokia, Illinois-based Helicopters Inc, the leasing company that owned the Eurocopter AS350 helicopter.
The station is a block from the city’s iconic Space Needle and is surrounded by high-rise office and apartment buildings.
Workers at the station rushed to the window when they heard the crash. KOMO reporters were then in the position of covering their colleagues’ deaths.
The accident sent plumes of black smoke over the Washington state capital during the morning commute on Tuesday.
Kristopher Reynolds, a contractor working nearby, said he saw the helicopter lift about 1.5 metres (5 feet) off the low-rise building before it started to tilt. The chopper looked like it was trying to correct itself when it took a dive.
“Next thing I know, it went into a ball of flames,” Reynolds said.
Witnesses reported hearing unusual noises coming from the helicopter as it took off after refuelling, said Dennis Hogenson, deputy regional chief with the National Transportation Safety Board in Seattle.
They also said the aircraft rotated before it crashed near the Seattle Center campus, which is home to the Space Needle, restaurants and performing arts centres.
Mayor Ed Murray noted the normally bustling Seattle Center was relatively quiet at the time. Had it been a busier day, “this would have been a much larger tragedy”, he said.
Investigators were working to document the scene and clear the wreckage, and will examine all possibilities as they determine what caused the crash, Hogenson said. A preliminary analysis is expected in five days, followed by a fuller report with a probable cause in up to a year.
Firefighters who arrived at the scene before 8am found a “huge black cloud of smoke”, and two cars and a pickup truck engulfed in flames, Seattle Fire Department spokesman Kyle Moore said.
Fuel running down the street also was on fire, and crews worked to stop it before it entered the sewer, Moore said.
An injured man managed to free himself from a burning car and was taken to Harborview Medical Center, Moore said. The man was on fire, and a police officer helped him to the ground and put out the flames, a police spokeswoman said.
Richard Newman, 38, suffered burns on his lower back and arm, covering up to 20 per cent of his body, the hospital said. He was in serious condition in the intensive care unit and will probably require surgery.
Two others who were in cars that were struck by the helicopter were uninjured.
Only the helicopter’s blue tail end could be identified among the wreckage strewn across the street.
