In the spring of 1953 a program of field reconnaissance for radioactivity in south-central Montana and northwestern Wyoming was authorized by the U.S. Atomic Energy Commission. Field procedures consisted of testing outcrops along roads, in cliffs, and around rim rocks, and testing mines, prospects and the dumps thereof with the appropriate instruments in an attempt to locate exposures of areas showing anomalous radioactivity and to ascertain the geological conditions under which such radioactivity occurred.

The goal of this National Transportation Safety Board study was to better understand the risk factors associated with accidents that occur in weather conditions characterized by IMC or poor visibility ("weather-related accidents"). The study accomplished this goal using the case control methodology, which compared a group of accident flights to a matching group of nonaccident flights to identify patterns of variables that distinguished the two groups from each other. This methodology expands on previous Safety Board efforts that have typically concentrated on summaries of accident cases. For this study, Safety Board air safety investigators (ASI) collected data from 72 GA accidents that occurred between August 2003 and April 2004.
