Know of a good aerial shot?

I'm putting together a sizzle reel and I need a really nice aerial shot. Does anyone know of a movie that features a really nice one? Actually, it could even be a nature show or whatever.

* flying over a forest, heading toward the horizon
* camera mounted on airplane or helicopter
* flying over forest treetops or something nature oriented
* no cars or people
* need about 15 seconds... up to 30 seconds if at all possible
* no words or titles in the middle of the frame

My biggest challenge in searching for this footage is the duration. Most clips like this in movies only go for about 3 seconds. Can't find anything with solid duration. I know it's a "long shot" (no pun intended) but I figure maybe this forum might know of something. Thanks.

I'd recommend going to a site such as VideoBlocks to find a video with the length/style/quality that you want. There's no doubt in my mind that you'll find something. I believe there's also times when they allow for free downloads.

BTW, if you can't find anything there, just go to any royalty free site (for video clips), and you'll probably find something.

There's a ton of stock footage companies and will have lots of options for you. Off the top of my head I'm pretty sure than iStockPhoto and Shutterstock have video libraries.
