Unexploded WWI Stokes Mortars Found at Airport

Several unexploded World War I-era Stokes Mortars were discovered at Pearson Field Airport in Vancouver, Washington, by an archaeologist during construction work. The mortars were found on Tuesday and Wednesday and were safely detonated by the Vancouver Police Department's Mobile Explosive Device Unit with assistance from U.S. Air Force personnel. Pearson Field, one of the oldest continuously operating airports in the United States, was home to the U.S. Army Air Service from 1923 to 1941, which may explain the presence of these munitions. The incident highlights the historical significance of the site and the ongoing issues of unexploded ordnance from past military activities. Local authorities ensured the safety of the site by following strict protocols for the identification and disposal of such devices.
