One gets the impression from the interviews on TV that this little jaunt was a spur of the moment deal and they did not think to tell anyone they were going or where. And did they carry an epirb and if they did have one how hard is it to activate it? Muppets comes to mind and maybe the young fella who said he now had second thoughts about aviation as a pastime has now had a light bulb moment more in line with his competence.
