When viewed from the ground in good visibility conditions, there is a strong possibility that you could see aircraft in cruise at distances of 30-50 NM (55-92 km) or more.

Planes have headlights so that pilots can see what is in front of them. Unfortunately, they are only effective during takeoffs and landings. Even with the slight illumination offered by the headlights, only darkness is visible when looking out the front window of a cockpit.
How do pilots see at night if airplanes don t have front lights? Starlight, moonlight, and ground-light can give good visibility of terrain, coastlines, clouds, and other things pilots need to see, without any light coming from the airplane.
It is perfectly possible to do the climb, cruise, and approach phases under instruments without any visibility. You look out the window, but all you see is fog, or black night plus fog. This is instrument flying, done under Instrument Flight Rules.
Doing some rough math based on that estimate, it's likely that there are anywhere between 7,782 and 8,755 commercial planes in the air on average at any given time these days. There is some seasonality to consider, though.
Whether flying at night or during the day, pilots need to see some kind of horizon. They use this to determine the airplane's attitude. At night pilots will turn their gaze from outside to inside and use the artificial horizon. The artificial horizon is normally a simply globe split into two hemispheres.
Yes, an aircraft can stay in the air without going forward if the oncoming wind, called headwinds are equal or greater than th minimum speed of that aircraft. This principle is used in the wind tunnels to experiment the flight characteristics by blowing the wind to the aerofoil and assess the aerodynamic changes.
At times like this, pilots will slow to a designated “turbulence penetration speed” to ensure high-speed buffet protection (don't ask) and prevent damage to the airframe. We can also request higher or lower altitudes, or ask for a revised routing.
