Auroral Corona over Norway : Higher than the highest mountain lies the realm of the aurora. Auroras rarely reach below 60 kilometers, and can range up to 1000 kilometers. Aurora light results from energetic electrons and protons striking atoms and molecules in the Earths atmosphere. Somewhat uncommon, an auroral corona appears as a center point for a surrounding display and may occur when an aurora develops directly overhead, or when auroral rays are pointed nearly toward the observer. This picturesque but brief green and purple aurora exhibition occurred last month high above Kvalya, Troms, Norway. The Sessyfjorden fjord runs through the foreground, while numerous stars are visible far in the distance. via NASA

Moar Science. :)
Seems obvious, no? Watch a well put together seven minute essay on why we need to change, and the sooner the better.
Nothing like being in the sweet spot for the necessity of complex landing procedures.
