> it's actually very hard to find a ship, even as large as an aircraft carrier, in the ocean
I just ran some googled numbers over my envelope, and I get that the Mediterranean sea (great circle distance between Gibraltar and Beirut is 2300mi) is about 14000x larger than the bow-to-stern length (858') of the carrier.
That's... not that terribly difficult as an imaging problem. Just a very tractable number of well-resolved 12k phone camera images would be able to bullseye it.
Obviously there are technical problems to be solved, like how to get the phones into the stratosphere on a regular basis for coverage, and the annoyance of "clouds" blocking the view. So it's not a DIY project.
But it seems eminently doable to me. The barriers in place are definitely not that the "empty space is just too big". The globe is kinda small these days.
And you've defined a harder problem! Once you've found it once it's much easier to find in the future: it can only go so fast, and it's constrained to stay in relatively deep water.
