The guys are right.....it's one one those motorised gliders with LED's on it.
I've watched them a lot.
How far away (feet/miles) can a light from a plane (military or conventional) be seen from the ground at night?

Although I can't imagine why but....do satellites have exterior lights for let's say either warning or navigational purposes (although that sounds ridiculous)?
How high up/far away (miles/footage) would you say the lowest satellite orbits?
Given your answer to the second question, would a person be able to see it from Earth? Remember, I am talking about night time only. So reflecting sun light is not part of the factor.
How bright would you say a standard navigational light be on a conventional or military plane? I tried Googling it but I kept reading 35-50 watts (at $500 per bulb) which can't be correct, can it? I have light bulbs stronger than that in my house.
How far can light travel (please break this down to layman terms because I do not understand light-years)?
I mean, how far away (altitude-wise) can someone on the ground see an exterior light on a plane?
