NTSB Says Pilot Drunk When He Crashed Into MT. Si

Posted: Updated:

SEATTLE, Wash. -The National Transportation Safety Board has concluded the pilot who flew his plane into the side of a Mount Si in 2012 was intoxicated. 

The NTSB says Rob Hill had a blood-alcohol content of 0.15 percent, nearly four times the amount allowed for a crew member on a civil aircraft.

 All three people aboard were killed when the single engine Cessna crashed into the mountain peak, about 30 miles east of Seattle. 

Hill, 30, was a flight instructor at AcuWings. A company spokesman says Hill took one of the company's planes from the Renton Municipal Airport without permission. 

The NTSB report says Hill and friends Seth Dawson and Liz Redling took off around 1:30 a.m. after attending a hockey game and going out to dinner.

Investigators say Hill crashed into the mountain in the dark.
