That's exactly like any migrating bird. Like a goose. Well, until they suddenly switch direction and continue at a constant speed and height till they go over the horizon. Have you ever seen birds migrating?

Also, if lights in the sky that look like meteors but suddenly switch direction are aliens, then I've seen them hundreds of times walking home from the pub (no streetlights here). Never yet been offered a lift!
