The history and geography change very little whether the bird was flying while I was sitting and looking above the monitor. This is what I meant with "meaningful way". Even though a building has storys, life on 12th floor isn't much different from life on second floor. In any case, much less different than life 20 years ago, or ten kilometers away from it. In a sci-fi story or movie we see lives really in 3D, planets wrapped in habitations and such. THERE you can and should count altitude as meaningful, but we're not really there yet.
