This MERS Research Program (MRP) Report No. 004 (MRP 004) was initially a research project on the 26 Civil Air Patrol (CAP) pilots and crew who lost their lives flying off the East and Gulf Coast shores of the United States searching for U-boats during World War II. Not anticipating the far greater impact that the CAP played during WWII, the list was expanded to cover the total of 70 CAP personnel who lost their lives while also towing aerial targets, delivering mail, participating in War Bond drives, etc. Further research on this research project reflects the dozens of other CAP personnel who were also killed while not on official duties or otherwise injured during WWII.
