Czech billionaire among 5 killed in Alaska helicopter crash

ANCHORAGE, Alaska (AP) — Federal investigators say a helicopter carrying five passengers on a heli-skiing trip in Alaska crashed into a mountain and then rolled downhill nearly 900 feet. The pilot and four of the five passengers on board died in the crash, including billionaire Petr Kellner, the richest man in the Czech Republic. The National Transportation Safety Board is investigating the cause of the crash just north of Anchorage on Saturday night. The bodies have been recovered, but an approaching snowstorm may stall efforts to remove the wreckage from the mountain near Knik Glacier. The crash site is only accessible by helicopter because of the rugged terrain and snowy conditions.
