One of my favorite aspects of flights to Europe (and there are very few; Europe is great, nine-hour flights are not) is the necessity of crossing over Greenland. When the weather is clear, the views of this icy alien landscape are just stunning. Our flight home from Paris in 2006 was one of those trips, with just a few clouds over the highest part of the (really big) island. So what do you all think of this glacial feature? What's going on here?
