Operated vs Located

The 2009 crash was a Canadian-manufactured, US-operated plane, located in the US.

The 2013 crash was a US-manufactured, Korean-operated plane, located in the US.

The operating county has far more ability to ensure pilot training, maintenance of aircraft, on-board safety procedures, etc.

E.g. the 2013 crash was due to mismanagement of altitude by the (non-US) crew, resulting in crashing short of the runway.
