I think even a 2d map with a dot for the object would be serviceable and neat in cases like this. Maybe draw the flight path in a swath that changes color over altitude. In example, think how meteorologists on TV use color on a map to show the how much rain has fallen. dark green -> green -> dark yellow -> yellow -> orange -> red -> blinking purple Just use a gradient with colors that won't interfere with whatever map you're using. Maybe just "yellow -> orange -> red" as it progresses to its target. Then once it hits it, switch to white, and continue to chart the movement as long as you broadcast.
