National Transportation Safety Board spokesman Keith Holloway said the reports released Thursday don't determine a cause or place blame for the crash that killed four journalists. That will come from analysis by investigators and presented to the NTSB board in the coming months.

The choppers from Channel 15 and Channel 3 were covering a Phoenix police chase on July 27, 2007 when they collided over a park and plunged to the ground. Both pilots -- Scott Bowerbank and Craig Smith -- and both photographers -- Jim Cox and Rick Krolak -- were killed in the crash.

The NTSB's preliminary accident report said witnesses indicated the Channel 3 helicopter was relatively stationary and the Channel 15 helicopter was maneuvering.

A lawsuit was filed in July on behalf of Krolak's son Colton.

The lawsuit assigns blame for the crash to ABC 15 pilot Smith and U.S. Helicopter Incorporated, Channel 3 reported.

Since the crash, news pilots told investigators they're talking more to each other and putting more distance between each other. When they're hovering, nobody moves until all other helicopters check in, an NTSB report said.

Monument Dedicated To Crews

Families and friends of four journalists dedicated a monument recently at the Phoenix park where the crews died.

In a tearful ceremony, fellow reporters, police and other city officials placed flowers along a concrete memorial that carried the pictures of pilots Scott Bowerbank and Craig Smith, and photographers Jim Cox and Rick Krolak.

Phoenix Mayor Phil Gordon said "the city's collective heart as broken" when the crash occurred. "And one year later while our sorrow is deep, we have come together, and as you've heard so many people have come together, to make this memorial such a tribute to our wonderful friends."

"In many ways, we count on them to begin our day," Kahn told about 300 people who attended the ceremony at Steele Indian School Park in central Phoenix. "We would see the good and the bad. We would know what and how to feel about the community and what to do to make this a better place to live."

The Valley came to know Rick Krolak's young son Colton during the tragedy and he spoke at the unveiling.

"We are grateful for the support from the community in this memorial which I hope will serve as a place of happy memories."

"I hope when people come here, it's not a reminder of the tragedy that we've all come to face, but a reminder of their lives and how good it was," said Colton Krolak.

Dedication of memorial, July 27, 2008

About 50 feet away from the monument is the spot where, exactly a year ago on July 27, 2007, a news helicopter from KTVK and another from KNXV collided in mid-air while covering a car chase. The choppers dropped in a fiery heap on the park's sprawling lawn.

Cox's father, Alan, said he was still angry about what happened.

"To send five choppers plus police helicopters in the same area is foolhardy," Cox said of the crash that killed his son. "Why not send one up? I'm still mad. It was a senseless act."

During the ceremony Cox told the crowd that the media should re-examine how it covers "non-newsworthy" events.

Ashley Guy, pilot Craig Smith's niece, said her family is appreciative of the support from the community for the family. "It gives us great comfort that all of you came here today to honor these great men and this helps their memory to live on forever."

3TV'S pilot Bruce Haffner said the memorial will be a fitting tribute to four Valley journalists. "And now, this park, I'll be able to fly over it and look down and think of those guys all the time in a happier mood."

Chase Suspect Held On $1 Million Bond

The man who allegedly started the chase, Christopher Jones, 23, was arrested later on the day of the crash after SWAT officers stormed a home in far west Phoenix where he had barricaded himself inside.

A SWAT team with canines made a forced entry, police said. Jones suffered a number of dog bites and was treated for the wounds.

As he was led into police headquarters in handcuffs, Jones had a few words for news camera crews.

"It wasn't a crime spree, it was an accident," he said. "I didn't even know what I was doing. I blanked out, dude."

Jones was booked into jail on July 27, 2007 on two counts of vehicle theft, four counts of aggravated assault on a police officer and one count of resisting arrest, with other charges expected to be filed later, according to Tranter. He made an initial appearance the next day.
