David, I'm a hobbyist and not an expert, but here is some info I found online, and a couple of suggestions on further research:
There is listed in the National Archives WWII Honor List of Dead and Missing Army and Army Air Forces Personnel a Captain John A. Urick, serial number O-397592, DNB (died, non-battle). His hometown is listed as Northumberland County, PA.
If this is him (I believe an air accident outside of combat would be listed as DNB), you may be able to get his personnel record through the NPRC in St. Louis. (They had a disastrous fire in 1973 which destroyed many records, but it is worth a try.) Info on that resource can be found at this web page: http://www.archives.gov/st-louis/military-personnel/index.htmlhttp://www.archives.gov/st-louis/military-personnel/index.html
You can also send for his Individual Deceased Personnel File (IDPF). As others in this forum have addressed, the info found in an IDPF can be graphic. If you pursue this resource, you should be prepared for that possibility. Send your request to: US Total Army Personnel Command ATTN: TAPC-PAO (FOIA) 200 Stovall Street Alexandria, VA 22332-0404 Be sure to cite the Freedom of Information Act in your request.
Some guidance on how to proceed with any info you acquire from these sources can be found at this site: members.aol.com/dadswar Info there will suggest that to find people who served with him, or to answer other questions about his service, your first order of business is to identify his unit, to the lowest level possible.
