Or, if you crash your airplane into the sea off Martha's Vineyard the Coast Guard and the Navy are mobilized to conduct an extensive search effort. If you're John Q. Public the Coast Guard would simply alert their personnel that a aircraft was reported missing ... and that would be the extent of the effort.
In addition, if you left a party where alcohol was served, put two other people in your plane and THEN crashed, an immediate burial/cremation would take place to ensure no autopsy is performed to determine if you were drinking.
