You weren't the only one who thought that the aliens had finally arrived. 

Drivers on I-75 near Grange Hall Road were stunned on Monday night to see a mysterious, strange light show in the sky. People were pulling over to get a good view and video of the lights - many thought that they were UFOs; others thought that maybe it was pieces of the Chinese space station breaking up on their descent back to earth.

In fact, it was neither of these: it was a drone light show, organized by Firefly Drone Shows out of Lake Orion. The group had permission to practice out of Holly Cloud Hopper's flying field.

The group wants to entertain people, but not cause any problems - they said to pull OFF the highway before you watch, not to the side.
