I'm surprised they didn't foam the runway first. Maybe they don't do that these days?

Isn't that foam stuff toxic? PFOS or something?

Yes, a fact I didn't know until EE found it.

There's a lot of toxic stuff associated with flying. Jet fuel and hydraulic fluid being the most common encountered by pilots. Not just spills, but blown lines.
