Why would anyone ask for the runway to be foamed? That’s a movie myth. The foam used by airport fire crews today is Aqueous Film Forming Foam (AFFF). It is designed to smother a fire, deprive it of oxygen, and cool the fire area. It has no purpose on a runway. What was the pilot hoping for, a slipperier runway? AFFF isn’t going to prevent any aircraft damage, and as we saw in this video, it is better in the truck so they can spray it on the airplane after it comes to a stop.
