This amazing picture was taken by Michael Ellis and posted on the Channel swimmers' discussion forums. With his permission, I've copied it here because it's just such an extraordinary image. You can see Dover harbour in the bottom of the picture (by the plane's engine), and in the top left, you can see the French coast. It looks so close!
Thanks for sharing this, Michael. I bet every Channel swimmer will have this on their laptop and phone for inspiration before the end of the day!
