Monday marked the second anniversary of the deadly Asiana Airlines plane crash at San Francisco International Airport. Amid ongoing lawsuits, changes are also in the works to review safety procedures.
Three teenagers from China died in the July 2013 crash of flight 214 while more than 180 of the 300 passengers were injured.
SFO was largely praised for its on-scene response to the plane crash. However, measures have still been taken since then to make things safer on the runway, such as fire department training and various studies done on the Asiana aircraft.
