I definitely think this song about heroin. Think about "I follow the sun with my silver plane" is like heating it on the spoon. And "Everything is white, it's so wonderful" would describe how your mind is often a blank when you're on heroin. Also, heroin makes you feel like you're everywhere at once, so feeling like a universal traveler would make sense. I know it makes no sense for Air to release such a song, but you have to admit that some of my interpretation makes sense.
