Old "proof" of UFO's ;)

Summer of 2017, regular flight in a mountain valley - nothing spectacular and just in the autumn looking at the footage I spotted the shadow - go figure

How weird is that, any ideas Alex?

 

[KostasNK]

The shadow of a helicopter passing in front and over the drone...

It gets even weirder when You put in to account that I was 100 m. away and neither hear nor see any plane oh copter not that they ever fly in the valley It's almost 2 years passed now I have No idea - did some measuring for travel and time and speed of the object should be higher than 300 km/h wich excludes "fast" clouds either

Leo satellite?

 

[zocalo]

It's clearly a weather balloon. Possibly swamp gas...

Maybe I was stalking you and it was my high speed drone shadow . But I can’t recall where I was that day .
Sorry I’m no help
