> some kind of metal detector sellotaped to the underside Been a thing since the 1970s, physics dictates dimensions though - you can go wrap or dangle: * http

  I've seen the 'dangle' type in action in the Netherlands last year (I was on the island of Texel for vacation); they were doing a project of mapping underground water if I recall correctly. Really interesting stuff. Would be neat if this could be automated and scaled up, I'm sure most of the world is as of yet unmapped with these kinds of detectors. Same with under the ocean.

  Awesome, thanks for these. I wonder if you couldn’t distribute heavier parts across a swarm - perhaps separating the sender and receiver(s) - running the wave at an angle (or many angles simultaneously) to the surface. The sources mention mostly aircraft, rather than drones, and human pilots aren’t as good as drones at flying in extremely tight formations, which might allow (if the tech allows in the first place!) parts to be distributed to work around pesky laws of flight.
