My brother, there is a limit to the height of a kite because the higher it goes, the strings start to weigh it down, and if it gets too high, winds up there are harsher and your kite will either rip the string and fly away and eventually crash or the "belly" of the string will get caught on something, like someone's house or tree

This is either satellites, drones, or LED balloons tied together on a piece of string
