SpaceX rocket carried 10 satellites into orbit from California on Friday, leaving a long trail which could be seen all over Southern California and as far away as Phoenix, Arizona.

This isn’t a new SpaceX rocket, either. Elon Musk‘s company used the same rocket to launch a bunch of satellites for the same company – Iridium Communications – back in June. The satellites are replacing older Iridium models, and will be used for global aircraft tracking and a ship-tracking service.

But the main yarn here is that trail, which appeared along with the setting sun and made people on social media and beyond think of everything from a UFO to a North Korean missile attack.

The pics and video from social look pretty great.

Look, you’d think there should be requirement that you inform people in the vicinity of what is about to happen before you launch a fuck-off big rocket into orbit. Just sayin’.
