I got called out to work on an incinerator at a helicopter blade manufacturing factory one time. It looked like fiberglass blades but I think they said it was carbon fiber. The producer boiled off the left over chemical into the air in the middle of Phoenix\Tempe because it was cheaper than paying for hazmat disposal. The county has an aggressive air quality control but they allow this as long as they get their permit fees. Lmao yeah cities are real healthy all right.
