I don't think you can make any statistical argument from accident data from a single year.

Yes, there is universal data out there. But those events are so rare that you almost never can differentiate a normal year from an abnormal one.

You absolutely can see a difference. [0] The term of art is "Runway Incursions", and the stats definitely show our airports are working at the limits of safety.

That's a 7 years graph, where category A incursions change by 0.7σ, and total incursions are basically horizontal.

What statistical conclusion are you taking from it?

		Category A and B incursions increased by 2.8σ. Further, it was 7 years of increases in a row. Either factor on its own would indicate a process out of statistical control.
