CLAIM-216221reported
“The investigator compared the reports with B-2/F-117 and possible experimental-aircraft explanations. A military explanation was considered possible but difficult because of the reported hover/slow speed, low altitude, sound and underside lighting; the case was labeled an unknown object of unknown origin.”
