“The helicopter carrying Kobe Bryant, his daughter, and seven others was trying to ascend above a fog-shrouded hill when it slammed into the ravine and dropped 2,000 feet per minute to the ground below, federal investigators said Tuesday.
Shortly before 10 a.m. Sunday, the Sikorsky S-76 chopper with nine people aboard climbed to about 2,300 feet seemingly in an attempt to clearthe thick cloud layer. It hit part of a ravine in the Calabasas and fell, crashing in an area on the hillside 1,085 feet above sea level, National Transportation Safety Board member Jennifer Homendy said.
The helicopter plunged into a steep descent with a rate of "over 2,000 feet per minute," making it a "high-energy impact crash."
"This is a pretty steep descent at high speed," Homendy said. "It wouldn't be a normal landing speed."
The time from descent to impact was about a minute, she added.
The helicopter was navigating a canyon with multiple hills and peaks, NTSB investigator Bill English noted, describing the area as a "ravine with undulating terrain."
"The main impact was about 20 to 30 feet from that small hill, but there were other higher hills surrounding it…it’s in a canyon with small hills within it," he said.....”
