I was doing a drone flight around the Basildon Ford tractor plant recently, mostly because it has an iconic water tower in the shape of an onion, when I found something that gave me a smile.
I noticed that there was an open hatch on the top so i zoomed in for a closer look.
When i got home I checked out some stills and noticed a bit of grafitti, right on the rather inaccessible top.
My guess is that a technician must have done this. You’d have to be a pretty balsy urban explorer to get to this in my opinion.
Just thought I’d share.
