Roswell UFO incident
In ufology, LaPaz's name is often associated with UFO investigations on behalf of the military during the late 1940s and early 1950s. These include Roswell UFO incident of 1947, the N.M. green fireballs, that began in late 1948 and continued through the 1950s, and the search for near-Earth orbiting satellites in 1954 along with fellow N.M. astronomer Clyde Tombaugh. However, only LaPaz's association with the green fireball investigations for the Air Force is thoroughly documented and a historical fact.
