Thankfully, the bride and groom laughed it off and no serious injury occurred:

Ok so here’s the story. This was shot using a DJI phantom and a gopro camera. This was two days before the wedding at their bridal shoot. This happened towards the beginning. I had done one successful fly by and i brought it around for another pass to make sure it was smooth. I underestimated the lift time and it hit the groom on the side of the face. He had a cut on his cheek and and the side of his head. I felt horrible. Luckily the bride and groom were able to laugh about it after and we continued the shoot. At the request of the bride and groom I put the video online. All though it sucks that this happened. I have decided to own up to what I did, instead of try to hide it from the world.

This is just a preview of what the world will be like in twenty years with five-year-old children piloting drones.
