Jamie Cooper, 33, claims that the unidentified object was spotted by his 13-year-old son James hanging over Ayr Harbour for around 15 minutes at 5.30pm on Sunday.
In the shaky 28-second clip a black entity, which resembles a chinook helicopter, is clearly seen hovering in the distance.
The dad-of-one, from Ayr, Scotland, said teen James sent him the footage after visiting the grocery store and was concerned by what it could be.
Jamie said: “James was walking home when he took the footage on Sunday, and sent it to me through Whatsapp.
“I have never seen anything like this before.”
