Really interesting video here (if badly edited) involving 100 small drone aircraft in formation. Intel had a great idea here it looks really fun and interesting but I wish they would’ve given more details inside the video.
If you really want to know what’s going on you have to read the article here.
They shot the video at Flugplatz Ahrenlohe, Tornesch, Germany. It actually was a guinness world record for the most drones in flight at once, which to me is much less interesting than seeing a coordinated drone lightshow.
