Haven’t I said how important it is to see London (and other cities) by night? Now you know why! Unfortunately, it won’t be easy to see it by night in a helicopter, but you have to start somewhere. 🙂

Wow, London is an amazingly beautiful city at night! Perhaps for your next trip there you can take an aerial tour? 🙂
I’ve never even looked into that, but these pictures make me want to. 🙂
