Planes

If you go to Wolfram Alpha and search for "planes overhead" you get a list of planes in the sky above your location, and a wee map showing them all. Apparently. I tried it, and there was nothing. That, or it did not work.
I wonder if it includes the International Space Station. Those in NZ may be interested in that. They dump their rubbish over NZ. See the article here. Carry an umbrella if the space station is up there. Those outside NZ may be interested because they don't have to worry!

What I like about searching on Wolfram Alpha is that you don't get all those ads. And you get the answer instead of a link to the answer. Well, the answer may not be what you expect...
