De-Icing at the Anchorage Airport

Not sure I've ever seen this orange de-icing goop before, although maybe
I've only previously noticed de-icing operations at nighttime.

De-icing fluid dripping down the window from the top of the aircraft.

It turns out that the orange color indicates that a Type I de-icing fluid is being used.
