Can you clarify the difference between these?

> first fatal crash of a US commercial airliner

> first fatal commercial airliner crash in the United States

Is it that the 2009 crash was a US-manufactured plane while the 2013 crash was not manufactured in the US but happened in the US?

Actually, the planes from both crashes were Bombardier, a Canadian company. The first one means operated by a US company and the second one refers to a crash in the US.

I believe the distinction the OP was making was foreign-owned/operated airline vs domestic. Makes a small difference, but not hufe, as all commericial pilots landing in the US must have an FAA ATP, and the same minimum flight hours as American pilots (though the quality of those hours and other training may vary).

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.
