It's a pity Landsat resolution is so low and the failed Scan Line Connector on Landsat 7 has trashed half of each image. Unfortunately, earth observing satellites only make an overpass every couple of weeks so it's like taking a photo of your backyard every two weeks and hoping to catch a mime there. If I actually went and wrote a script to identify (say) circular objects that don't appear in subsequent frames and had say millions of dollars worth of GeoEye data to sift through, I would probably wind up with millions of hits of anomalously shaped clouds, circus tents, hot air balloons, bolides and suspicious mimes. Meanwhile, I still wouldn't be able to catch a daytime UFO which probably wouldn't look like the spectral signature or shape of what I imagined it would. Then I would wound up with a blurry picture of a UFO to post on Unexplained Mysteries and people would be going "see!? the alienz are here! my spirit fairy guide told me so! abduct me!" and all the skeptics pointing out that it is just a blurry photograph of a UFO which proves nothing.
Seriously, you'd be better off using remote sensing to look for instances of ball lightning.
All of this assumes the aliens are morons who can hide from tourist cameras but not realise that we have satellites on predictable orbital paths. Our level of remote sensing capability gives us just a hint of what any prospective alien visitors could muster up. With a modest level of computing power and reasonably sized telescopes or some equivalent like phased arrays, they could monitor the movements of every single person and piece of equipment on Earth - most notably Earth-based telescopes and cameras.
The problem with actually discovering and studying UFOs is that our imagination and knowledge base is simply not up to the problem. We don't know enough to actually narrow down our search to usable parameters. We only know what UFOs are not, and our attempts to classify them as alien spacecraft (e.g. STL with a fusion-based drive) inevitably leads us to our own prejudices with our technology.

However, Landsat is one of many, it might not be capable alone, however, in addition to the eight landsat missions, we have another 10 or so similar programs, private enterprise has double that or more, NORAD, Polar Satellites and GOES programs. I do not think an Alien would be a moron to not know these are there, after all, they, like us, are seeking the unknown. I canot buy into the uber brilliant advanced species, they cannot all be like that. We have had the capabilities to reach the stars fro a long time, we just did not take that leap, another species is likely to considering the statistics for life. And again, the amateur community is what I feel the best bet would be, yet this is the most silent of communities where this subject is concerned, some astronomers have reported UFO's, I realise that, but again, considering the numbers involved, this is an insignificant contribution which like the rest of the phenomena from descriptions to photographs, is very fuzzy. Each individual works on the spur of the moment, I myself scan the heavens, which I do not see as predictable. Radio telescopes are impervious to light refraction, we just monitor too much for things to be slipping past us on a regular basis. Especially with the breaches of such purported stealth are a regular item, but only within the atmosphere, never outside of it, or heading towards it.
Rather than a clear picture from a satellite, anything showing a space-bound trajectory, incoming or outgoing would be something to add, but no such thing exists, not by any trackable means, yet within the atmosphere, these things seem to breach RADAR. That seems to not make sense to me. If they are advanced enough to know the location of every person on earth, then the tales of crashes and RADAR tracks seem extremely unlikely to be connected to the ETH at all.
Whilst I agree that our knowledge might not be up to the task, I fear our imagination surpasses it. I have little doubt that the UFO phenomena, and in particular the ETH is very much over-thought. The phenomena no doubt has many answers, I think we need to look beneath out feet before we decide these occurrences are caused by unknown forces from the heavens. We know that some things that used to be considered UFO's are these days IFO's (sprites, plasmas, earthlights), and there are still many to learn more about, I agree, but I do not see a reason to reach further than out own world at this point i time, the evidence is simply not compelling enough to invoke ET.
