Official Probes If Rescuers Ran Over S.F. Plane Crash Victim, Teen From ChinaPilots of Asiana Flight 214 were flying too slowly as they approached San Francisco airport, triggering a control board warning that the jetliner could stall, and then tried to abort the landing seconds before crashing, according to federal safety officials. Investigators also said they were looking into the possibility that rescue crews ran over one of the two teenagers killed in the crash on Saturday. Officials released the details without explaining why the pilots were flying so slow — or why rescue officials didn't see the girl. The Boeing 777 was traveling at speeds well below the target landing speed of 137 knots per hour, or 157 mph, said National Transportation Safety Board chief Deborah Hersman at a briefing Sunday on the crash.
