My A&P mechanic works a day job, in addition to doing small-plane
maintenance. He is in charge of local maintenance on DC-9s that fly
for a major freight hauler.

Our part of the world got hit with a pretty decent winter storm over
the weekend, which resulted in "his" DC-9 being coated with over 1/4"
of ice before it started to snow. In order to remove that ice before
departing, they had to spray over 1,800 gallons of deicing fluid on
that single DC-9.

And, since this isn't being done at a major airport (which would have
deicing stations to catch all that stuff), there is no recycling of
that fluid. It just goes away...all $3600+ worth of it.

One could only wish that it would "go away". Unfortunately, it's being
stored for some future generation to deal with.
