Graphics forum: Landscape videos and similar in HD - where or how?

Good day.

I realize this is maybe not the best place to ask this, but it's not completely off either: I'm currently interested in watching some landscape videos, like the view from a train cab that just shows the train view while it travels from point A to B, or some bird eye perspective out of a zeppelin; simply videos about all kinds of nice perspectives in the world, to get that kind of adventure feeling on the go. The sight should be changing, like a train or zeppelin view does naturally since the vehicle moves while filming, and it also should be in HD, at least 720p better 1080p. It can have background music, but natural sounds would be better. And it should be more than a few minutes clip.
I found it close to impossible to find anything on the web that meets my criteria; usually all I can turn up is lot's of unrelated stuff or some one trying to sell me something. And also youtube, but I don't really like it; almost always low quality, here and there advertisement, never longer videos.

I often see footage like I desire around programs like NBA games; "Good Year" seems to have a Zeppelin that provides air footage of cities sometimes, for example. Is there nothing on the Internet that meets my requirements, and is hopefully free too? Is the demand after stuff like that really that low? Or do I just search wrong?
And if you can't help me here, do you know where else there might be guys who have answers for me?

Really hope you can help me out guys, I would appreciate it much.
Longing for adventurous footage, Yours
