San Francisco Fire Chief Joanne Hayes-White and Assistant Deputy Chief Dale Carnes both raised the possibility at a news conference with first responders, according to an Associated Press report (http://wapo.st/1a6sufC).
The plane, a Boeing 777 from Asiana Airlines, touched down tail-first and crashed just short of the runway on Saturday.
The majority of people on the plane survived the crash, though several were critically injured. Two teenage girls were killed.
