While I was chatting to a local couple about the Swifts a bi-plane came by. It was only when I looked at the picture when I got home that I found out that it was a US Navy plane. I don't know if this was connected to the Deal festival but it gave us a close look.
Soon after the Coastguard plane come close along the cliff top and it did several passes while I was there. I don't know if there was an incident or it was just on patrol duty, but either way it came close enough to see the face of the pilot!
