Black Kite?

I saw a small bird of prey flying over my school which I am quite sure was a Black Kite. Of course, I wasn't allowed my camera, and I didn't have time to get my binos so I used my friends, which are worse.

When we did get a full view I didn't have the binos, so I only got to see flying away. It had a light brown back, less prominent fork tail and looked a bit like a harrier. In my area, I have only recorded 4 birds of prey, and most of them as expected in a woodland habitat. Red kites and buzzards are regular, than I had one sighting of some peregrines at school and lastly I have a Tawny in my garden.

Anyway, I wasn't very sure, as I obviously didn't have the time to go around the country looking for them and sort of just gave up on rare birds. I was hoping someone might have seen a Black Kite and could help.
