During World War II the Japanese constructed nearly 10,000 lighter-than-air balloons for the purpose of carrying destructive pay loads to the U.S. Between November 1944 and April 1945 these balloons made use of the prevailing west-to-east jet stream over the North Pacific Ocean. Nearly 285 sightings and fragment findings have been recorded in North America, and 5 deaths resulted. This was the first and only attack upon the American continent directly from an enemy homeland.
