All search is not equal. A lost child will almost always have a significant search, but an attractive child of a wealthy, famous, and attractive family will get a better publicly funded search than a poor child. A woman will generally get a better search than a man, and a childless middle-aged man taking risks should not expect the most massive of searches.
Dr. Gray, a wealthy researcher lost at sea, is receiving a grade A publicly funded search, as well as the extraordinary private resources of an extremely wealthy community. I'm a bit jealous, but only a bit. Whatever it takes, I'll root for the miracle.
