about 357 km or 222 miles depending on the visual acuity.
Passenger planes generally fly at an altitude of about 33000-37000 feet. Smaller planes fly much lower, while military jets have the capabilities to fly higher.
"1 feet" is not a proper term. It is either "one foot" or two or more "feet." Sometimes you will see "1 feet" on forms or other places, because the person who made the form or whatever did not make it so that the word would change to "foot" when it was just one. But it is still incorrect to say "one feet."

Try an airplane. Answer As I have thought was to build a sail boat and put it in the ocean and see how far it will take me.
Loons, like most creatures have 2 eyes, so the formula will be radius of their eye, times how far they are away, that will be focus. About 25 feet, they will be able to see about 35 feet with a dim outline on land
The running lights are more for other pilots to see you than for you to see anything. They do not help the airplane fly any better.
five to eight feet
You can see them at many airports and in the sky.
i think echolocation cango up to 100 kilometers
Because the speed of light is about 874 thousand times the speed of sound. If the airplane is flying at 30,000 feet above you, then you see it from where it was 0.000031 second earlier, but you hear it from where it was 26.9 seconds earlier. By the time the sound reaches you from where it was, it's moved far from there.
Depends on if they are standing in front of a tree. If so, then not very far.
