We, as well as most people, call them planes.
No, they're not airplanes. Airplanes do not show in the night sky as a "moving star" (since there is no sun), they flash in red (unless you've never seen an airplane). Moreover, Why all these airplanes would do the same curved trajectory in the visible sky ?
And I add that I've seen such a "moving star" in a region of the world where there is no high airplane traffic.
You would fool me by saying these are airplanes, but I would tell you that I have a software that predicts all satellites' trajectory. Having seen a moving light, I hurried to this software and really it showed me that it WAS a satellite, in the SAME direction, SAME position and SAME speed that I've seen with my eyes.
I think it's time you stop this ridiculous thinking.
