I am writting to you to inform you of a photo that I have found. Believe it or not, it was taken for the BBC. I love science of any kind and am an avid viewer of nature films. Recently, I borrowed my sisters copy of Planet Earth the complete series. This is a 5 DVD set. On the back panel of the DVD cover, in a picture of what I assume to be Victoria Falls, I found something that looks like a craft either going into or out of the falls. At first I thought that I was seeing things. I even tried to wipe it off with a damp cloth. I then went and got my magnifying glass and too a closer look. Not certain, but it may be a craft of some kind. If it is, it's like nothing I have ever seen before. I would really like to know what you think of it.
