(CNN) -- Asiana Airlines Flight 214 was seconds away from landing when the passengers sensed something horribly amiss. The plane was approaching San Francisco International Airport under a beautifully clear sky, but it was flying low. Dangerously low. Benjamin Levy looked out the window from seat 30K and said he could see the water of the San Francisco Bay about 10 feet below. Even for an airport where landing strips run close to the water, the descent seemed alarming to the San Francisco man. "I don't see any runway, I just see water," Levy recalled. Further back in the Boeing 777, Xu Das had the same realization.Flight recorders have been found, the NTSB saysAsiana identifies the two 16-year-old girls killed in the crash182 people were hospitalized, while 123 were uninjuredPassengers say the plane's rear struck the edge of the runway
