The National Transportation Library of the Department of Transportation has digitized numerous collections to provide easy access for DOT library customers and researchers. In that array of valuable research materials are the investigations of aircraft accidents from 1934 – 1965, the investigations of railroad accidents 1911 – 1993, and much more. Here is the link to the DOT library’s digital collections.
Of particular interest to researchers are two commercial airplane crashes in Cecil County. One involved an Eastern Air Lines Flight that took place near Bainbridge Naval Training Center on May 30, 1947.  The other involved Pan American World Airways, which occurred at the edge of Elkton on December 8, 1963.
We had previously linked to those materials at the digital library but since readers often report trouble with the links, we are providing copies of the official Civil Aeronautics Board investigations here.
