In the features Project Sign, and Project Grudge, we saw that, after General Hoyt Vandenburg rejected the conclusions of Project Sign's 1948 "Estimate of the Situation" as being unfounded, the attitude of the Air Force toward UFOs changed. The name change of its official agent for UFO investigation changed on 16 December 1948 from Project Sign to Project Grudge reflected this change in attitude, as did the final report of Project Sign.
