I have taught my kids how to use the VHF handheld and a high chart to call
airliners. I actually used this once when camped out in my seaplane. The
weather came in and we couldn't get out for two extra days.

It was no big deal because we were VERY well equipped and I needed to use up
the survival food anyway. But I called a passing airliner I heard on
frequency. I asked the pilot to please give my wife a call and tell her we
were OK and that there would be a delay. He did and we flew out two days
later.
