The Robert J. Collier Trophy is an annual aviation award administered by the U.S. National Aeronautic Association (NAA), presented to those who have made "the greatest achievement in aeronautics or astronautics in America, with respect to improving the performance, efficiency, and safety of air or space vehicles, the value of which has been thoroughly demonstrated by actual use during the preceding year." The trophy was stolen briefly in 1978, but was recovered. The thieves left it at Fort Foote park and it was recovered 26 hours from the time it went missing.
