Perhaps they could get an FCC waiver to use Flarm in the Worlds task

I'm not sure they would consider this, as the problem isn't the FCC but
definitely their fear of those insane US liability lawsuits. Why else
would they prohibit the use of FLARM not only in the USA but worldwide
when there is a US citizen on board?
