Down the drain by Antonis Deligiannis, on Flickr

Looking at this from the air,was like looking a very big drain of a sink!

Taken with my DJI Mavic Air 2

Down the drain and round the (U) bend

Great find/framing!

Great Shot    

I like it a lot!

Great shot.    Indeed it does look like a big sink drain pipe.
