LOS ANGELES _ Federal investigators on Monday began to try to unravel the mystery of why a helicopter carrying Kobe Bryant, his 13-year-old daughter and seven other people slammed into the side of a hill in Calabasas.
Firefighters responding to a 911 call at 9:47 a.m. found a debris field in steep terrain with a quarter-acre brush fire. Paramedics arriving by helicopter searched the area but found no survivors.
Bryant, who lived in Newport Beach and Los Angeles, was known to keep a chartered helicopter at Orange County's John Wayne Airport.
A Sikorsky S-76 chopper, built in 1991, departed John Wayne at 9:06 a.m. Sunday, according to publicly available flight records. The National Transportation Safety Board database shows no prior incidents or accidents for the mid-size helicopter.
Parts of Southern California were enveloped in thick fog as the helicopter made its way from Orange County to Los Angeles. During the flight, the pilot requested permission to fly while being monitored by air traffic control, a situation called "flight following," according to radio communications between the air tower and the aircraft. The tower is heard telling the pilot the chopper is too low before the conversation ends. There did not appear to be a distress call.
Bryant was scheduled to coach Sunday in a game against the Fresno Lady Heat at his Mamba Sports Academy in Thousand Oaks and was en route there when the helicopter crashed. The tournament, called the Mamba Cup, featured boys' and girls' travel teams from fourth through eighth grades. Bryant's daughter Gianna, who attended Harbor Day School in Newport Beach, was scheduled to play.
The Federal Aviation Administration and National Transportation Safety Board are investigating the crash. The FBI is also assisting in the probe, which is standard practice. The helicopter was registered to Fillmore-based Island Express Holding Corp., according to the California secretary of state's business database. The helicopter's manufacturer, Sikorsky, said in a statement Sunday that it was cooperating with the investigation.
The National Transportation Safety Board was dispatching a "go team," a squad of investigators that responds to major accidents across the country, said Christopher O'Neil, an agency spokesman. Leading the investigation is Jennifer Homendy, an NTSB member who oversaw the investigation of a fire aboard the dive boat Conception that killed 34 people off Santa Cruz Island in September.
Experts have said weather conditions and possible mechanical issues will likely be at the top of the list for investigators.
The fog was severe enough Sunday morning that the Los Angeles Police Department's Air Support Division grounded its helicopters and didn't fly until later in the afternoon, department spokesman Josh Rubenstein said.
"The weather situation did not meet our minimum standards for flying," Rubenstein said. The fog "was enough that we were not flying." LAPD's flight minimums are 2 miles of visibility and an 800-foot cloud ceiling, he said.
The L.A. County Sheriff's Department made a similar assessment about the fog and had no helicopters in the air Sunday morning "basically because of the weather," L.A. County Sheriff Alex Villanueva said.
Witnesses said they heard a roar before the chopper slammed into the hillside Sunday morning.
Jerry Kocharian, 62, was standing outside the Church in the Canyon drinking coffee when he heard a helicopter flying unusually low and seeming to struggle.
"It wasn't sounding right, and it was real low," Kocharian said. "I saw it falling and spluttering. But it was hard to make out as it was so foggy."
The helicopter vanished into the sheet of fog, then there was a boom and "a big fireball," he said.
"No one could survive that."
Scott Daehlin 61, was taking a break from setting up sound for a service at Church of the Canyon, which is below the crash site, when he heard the helicopter overheard.
"Because of its proximity to the ground, I knew something was wrong. It was hovering real low, like they were searching to land. It was making a slow left turn. It was about 9:44 a.m., and then the impact happened. I heard a crunch. I don't think it pancaked. I think it hit rotors first," Daehlin said. "I immediately called 911."
The pilot and eight passengers _ including Bryant and his daughter _ were killed. Orange Coast College baseball coach John Altobelli, 56, his wife, Keri, and their daughter Alyssa, who played on the same club team as Gianna, also were killed. Christina Mauser, who was the top assistant coach of the Mamba girls' basketball team, as well as a mother and daughter from Orange County, identified by family and friends as Sarah and Payton Chester, also died in the crash.
Officials say the recovery effort at the crash site is expected to take days.
Villanueva said people have flooded into the area of the crash, some going into residential neighborhoods and trying to get to the remote hillside where the helicopter went down. He said the traffic was making it harder for investigators and emergency personnel to do their jobs.
"It is off-limits to everybody," he said of the crash site, noting that the FAA has a 5-mile no-fly zone around the area up to altitudes of 5,000 feet. "People, stay away."
