A lot of people think they're the ugliest planes around. I'm not one of them; I think it has a certain grace. I live on one of Heathrow's flight paths and I'm still impressed when one flies over. It's impressive that they can get into the sky (forgetting the An-225 for a moment).
They're bloody noisy though because they fly so low. Heading from London to the Middle East you're somewhere over Turkey before you reach altitude. Or at least it seems like that.
