The NTSB finished their interviews with the four pilots of that doomed Asiana flight. Three were in the cockpit at the time of the crash, the fourth was in the cabin.
We already knew that the pilot was inexperienced on the 777, he was about half way through his real life training. Turns out his supervisor, the co-pilot, too was inexperienced, not flying the 777 but as an instructor pilot.
Meantime, the pilots believed they'd set the auto throttles to the appropriate landing speed of 137 knots or 157 miles per hour, instead the plane dipped to about 122 miles per hour. NTSB Chair confirmed that looking at the auto throttles, they were armed. But that doesn't immediately validate the pilots' claims. She says, the NTSB will look at the different possible ways the auto throttle can be engaged.
From Susan Hirasuna:
The latest developments in the NTSB investigation into the crash of Asiana flight 214 revealed the pilots initially told cabin crew members to keep passengers in their seats. Only after one flight attendant reported fire and smoke did they deploy emergency chutes. Two opened properly, but two others deployed inside the cabin after the plane second hit to the ground.
Two flight attendants were pinned under the chutes; one of them was injured with a broken leg. Did a bright light briefly blind the pilot as he was landing the plane? That's what he told the NTSB. It adds to the investigation with the agency also looking more closely at the auto throttles and auto pilot. Apparently, there are multiple ways that the auto pilot and throttle can be engaged; so the NTSB will work with the plane's maker Boeing to figure how those various permutations may have factored in the crash.
