Oh yeah, like an observation platform. That's probably the only way you'd be doing time travel anyhow since it's also space travel because the Earth now isn't where the Earth was 200 million years ago; doing an atmospheric re-entry across time when you're not 100% sure where exactly everything will be sounds like an occupational health hazard and inadvisable at best. Gods fucking help you if anything goes wrong and you violently scatter pieces of your fancy time machine across a few square km of densely populated (by animals including genus Homo) area.
