they flew over crashed and dissapeaREDme and my girlfriend were traveling from western australia to south australia. we were driving along the nullabor plain when four highly lit up disk shaped objects in formation flew straight over the top off our car at about im guessing 350 km an hour and it was getting faster. my car stopped running as soon as they passed over then all of a sudden there was a big what felt like a energy wave and one of the ufo's broke from the formation and crashed far away in the distance. when it made contact with the earth it exploded and a orange light shot back up into the sky and disapeared.
