Drone Records a UFO’s Supersonic Flight in 4K Resolution

The following video is absolutely stunning! It shows a UFO flying at low altitude  and supersonic speed above Silicon Valley, California.

The video was recorded by a 4K ultra-HD camera, attached to a DJI Inspire 1 drone.

The experts who analyzed the video estimated that the unidentified flying object was probably metallic in nature – as it reflected sunlight – and it was silently moving at a speed of 1500 – 2000 miles per hour.

One YouTube user estimated the distance traveled as around one mile every one to two seconds.
That would give it a speed of around 2890 km/h (i.e. 1800 miles/hour), roughly 2.4 times the speed of sound.

You can watch the video below (adjust the resolution to 4K and watch it a few times, as it only lasts five seconds):

And here you can watch it in Full HD and x25 slow motion:
