Through the month of June, the National Transportation Safety Board reports there were 861 accidents in all of U.S. civil aviation with 294 fatalities. Among air carriers, there were 57 accidents and nine fatalities.

Air crashes require investigation and air crash investigators require training. In this edition of Dateline, VOA's Tom Crosby talks about the education of air crash investigators with Eric Adams, Associate Editor of the Smithsonian Institution's Air and Space Magazine. Mr. Adams was in Oklahoma to report on a class of prospective investigators. He told Tom what he had learned.
