I was expecting a pic of a top secret space plane.

Wow, that is a wicked picture. That would make an awsome background.

That's a neat picture. But what's even better than that is sitting on my roof and watching it crawl around only twenty feet above my head!

Your house is at 100,000 feet elevation?

Awesome pic. Reminds me of the time when I was doing reconnaisance...oopps..um...nevermind.

 

[Pliablemoose]

Awesome.

I was examining this phote and if you look to your bottom left you can see a circle. Weird, perhaps it could be a UFO.....oooOOOOoooOOooo

Not exactly... The aurora activity in that picture may be very high in elevation, but just like clouds, aurora activity changes in elevation, moving vertically just as it does horizontally.

yes, I'm sure it varies in altitude a bit. However, the ionosphere doesn't even begin until 50 miles high. This page says that auroral activity peaks around 100km, or 60 miles above sea level. You can add a whole lot of variance to that to that, and say that an an aurora may occur anywhere between 20 miles high and 200 miles high. Even if this is true, which I doubt, you're still off by about 100,000 feet. The ionosphere is not 20 feet above your house.
