One might wonder about some aspects of the search effort, as well, although the searchers evidently faced some significant obstacles. Did they know anything of their plans? They could have been confronted with a very large, poorly defined search are if the couple's objectives were unknown.

Still,searching for several days? how is it that the couple was finally making some noise, leading to their recovery? People who make themselves conspicuous, one way or another, improve their odds considerably.

It would be useful to read a constructive critque of the incident, but those are rarely available.
