NPAS (National Police Air Service) St Athan (South Wales) reported a strange sighting in the sky over the Bristol Channel at 9.30pm on 17th September.
The black sphere could not be seen with the naked eye but the fact it was heat-emitting allowed it to be captured by their camera - which reported it as ‘black hot’. Nothing was confirmed by Air Traffic Control, so this seems to have also been completely invisible to radar.
Any suggestion?? Nothing seen by local ATC… 👽?? pic.twitter.com/Hu07DLmn3z
