SAN FRANCISCO—Asiana Flight 214 makes its final approach after a 10-hour flight that started in Shanghai and stopped in Seoul. A preliminary review of the crash by federal investigators turns up the following:

— APPROACH PROCEEDS NORMALLY ... the plane receives clearance from air traffic control to land without its instrument landing system. Visibility is about 10 miles with winds out of the southwest at 7 knots. There are no distress calls or requests for support in the air traffic control tapes that captured the discussion between a controller and the Asiana crew.

— SEVEN SECONDS OUT ... the crew asks to increase its air speed. National Traffic Safety Board chairwoman Deborah Hersman says the plane came in well below the approach speed of 137 knots that crew members had discussed.

— FOUR SECONDS OUT ... the stick shaker, a yolk the pilots hold, begins shaking, indicating the plane could stall.

— 1.5 SECONDS OUT ... the crew calls to abort the landing and go around for another try.

— CRASH ... the plane hits a seawall. The controller declares an emergency. The pilots talk to air traffic control and emergency vehicles are deployed.
