Saskatchewan Filmmaker Documents WWII Japanese Balloon Bombs Sent to North America

HYDROGENDEFENSE

Scott Woroniuk's documentary explores the deployment of 9,300 hydrogen balloons by the Imperial Japanese Army during World War II, which carried four incendiary devices and one anti-personnel bomb each. These balloons were released over the Pacific Ocean between 1944 and 1945, utilizing high-altitude air currents.

The operation was initiated in response to the 1942 Doolittle Raid, marking the U.S.'s first retaliation after Pearl Harbor. An estimated 1,000 balloons reached North America, with only 300 documented across Mexico, the U.S., and Canada.

Notably, the first balloon found on Canadian soil was in Minton, Saskatchewan. The operation's design minimized risk, as no pilots were involved, and the balloons were intended to disintegrate after dropping their payloads.

The only confirmed casualties occurred on May 5, 1945, when six civilians were killed in Oregon. Woroniuk highlights ongoing discoveries of these bombs, including recent finds in British Columbia.
