Why do flights go over the North Pole?
Thank science: In order to prevent the aircraft’s fuel from reaching its freezing point of around -50 degrees Fahrenheit, transpolar flights occasionally descend to a lower altitude over the Arctic, sometimes by as much as 10,000 feet, to an altitude ever so slightly warmer for the fuel—and ever more picturesque for …

Why don’t planes fly in a straight line?
When traditional flat maps are made, distortions occur when the sphere is made flat. Those flight paths that don’t appear straight on a flat map will look quite straight if you look at them on a globe. Instead of relying on flat maps, airplanes follow “great circle” routes that account for the curvature of the Earth.
Why do airplanes not fly over Antarctica?

Something called ETOPS (Extended Operations) governs how far from an emergency diversion airport certain aircraft are allowed to fly, according to its model.
Why do planes not fly over Tibet?
The leading reason for aircraft avoiding the region is the high average height of the terrain. This is over 14,000 feet. Aircraft, of course, cruise much higher than this. But the procedure in the event of an emergency such as cabin depressurization is to descend to 10,000 feet before diverting to an airport.
Why do jet planes leave a trail?
Jets leave white trails, or contrails, in their wakes for the same reason you can sometimes see your breath. The hot, humid exhaust from jet engines mixes with the atmosphere, which at high altitude is of much lower vapor pressure and temperature than the exhaust gas.
Why can’t we go to the South Pole?
