That's what it looks like to me, as well. That was actually the first thing that came to mind, that it looked like the warning symbol for radiation.
Edited to add:
I hit enter to soon. I meant to add that even though that pattern looks like the radiation warning symbol, I don't think it has anything to do with radiation. It's just similar to common aerial search and rescue patterns, which is what I think it is.
Possibly people who were in a boating accident or something similar. Or they could be doing surveillance on possible smugglers/traffickers. Or it could be a training session.
There are plenty of legitimate reasons to pick from.
Everything doesn't need to be part of some evil conspiracy. It is within the realm of possibility that it has absolutely nothing to do with anything nefarious and that it's not part of a secret message to us.

Double meaning? If its simply just a search pattern, that begs the question..... What are they looking for....?
