Living in the center of France, we are under a major southbound flight path from Paris, London, Brussels, Amsterdam, and other northern cities. The destinations, I imagine, are places like Lyon, Bordeaux, Marseille, Nice, and points in Corsica, Spain, Italy, North Africa, and beyond. This view of our piece of the sky is typical in the mornings around eight o'clock.
Most of the flights I see are going south. There are some northbound planes, usually more to our west than right over us. Sometimes, usually on a summer evening, I can see the sun glinting off an airplane as it passes overhead. And in the night sky the flashing navigation lights compete with the stars for attention.
