Watch This Plane As It Makes Its Landing In Greenland

An interesting part of the video is the runway 
which is ice-free even if its surrounded by tons and tons of ice. 
I wonder how they keep this airport safe for aviation. 

With there's ice on the runway, any aircraft can skid off while taxiing, 
and landing too will be dangerous.  
Planes take longer to slow down in icy runways 
because of so much less friction or the lack of it. 

Therefore,
airports must have some type of de-icing mechanisms or equipment
to keep them free of ice and thus safety for travelers. 

This is a nice and cool video to watch below.
