OKLAHOMA CITY (AP) — A National Transportation Safety Board report says a witness reported seeing a flash in the sky before a helicopter crashed near an Oklahoma City nursing home last month and killed two people onboard.
It's not clear what could have caused such a flash. The preliminary report, released Wednesday, does not spell out why the helicopter crashed on Feb. 22, killing the pilot and a flight nurse. The third person onboard was seriously injured.
Investigators say satellite data showed the helicopter leaving from a helipad at Integris-Baptist Medical Center in Oklahoma City, but the data stopped less than four minutes into the flight.
The report says the helicopter was headed to Watonga, about 70 miles away, to transfer a cardiac patient to the University of Oklahoma Medical Center.
