Physical problem ash would get into everything (engine intakes, air condition systems: regions close to caldera would be buried area would be uninhabitable, cleanup of less-affected area would cost into the billions of dollars, 2. Air traffic ash would coat jet turbines causing them to shut down in mid-flight: 3. Breathing anywhere ash falls would be difficult without protection. Toxic chemicals would coat the ash partials.

The risk of a super-eruption at yellowstone is low at the present time.
