A news helicopter crashed on top of at least three vehicles at Seattle Center Tuesday morning and caught fire, killing two people and critically injuring a third person.

KOMO-TV confirmed it was their helicopter. The helicopter was being used in a joint partnership between KOMO and KREM 2's sister station KING 5.  The helicopter is managed by Helicopters Inc, also known as Heli Inc. The company specializes in the design, construction and leasing of news helicopters for television and radio stations nationwide.

KOMO News said the copter was apparently coming in for a landing on its rooftop Tuesday morning when it possibly hit the side of the building and went down, hitting several vehicles on Broad Street.

The copter and cars exploded in flames. The Seattle Fire Department reported two people were pronounced dead on arrival.  Firefighters also reported a 37-year-old man was taken to Harborview Medical Center in critical condition. That man was in one of the cars, but managed to pull himself out.

People in the area reported seeing a huge cloud of smoke as firefighters and police responded.

The FAA and NTSB planned to use recordings of air traffic communication to help determine what caused the crash

UPDATE:

A National Transportation Safety Board team is in the early stages of investigating the crash. NTSB official Dennis Hogenson says they are looking into all possibilities at this point.

Hogenson said he will have a preliminary report on the crash in five days.
