With no other options and complete cloud cover what would you do though?
In the absence of radio failure, the other option is
talk to someone. Call Mayday on 121.5. Tell them that you've screwed up, that you're in the ...., that you'd like some help getting down alive. Worry about the paperwork later. Surely to goodness do this before trying to let down in cloud over the sea
or land without the appropriate qualifications!!
