Terre Haute CAA and Nearby Pilot Object Reports
October 9, 1951Terre Haute-Paris corridor, Indiana / Illinois, United States
CAA aviation specialists at Terre Haute Municipal Airport reported a flattened round object crossing overhead; about two minutes later, a nearby private pilot reportedly encountered a hovering flattened-sphere object that accelerated away when approached.
Claims are displayed with the source wording, locator, relationship and verification state. Competing claims remain separate rather than being averaged into a single answer.
“CAA specialists R. L. Messmore and C. W. Sonner reported a flattened round object crossing Terre Haute Municipal Airport; about two minutes later a private pilot near Paris, Illinois, reportedly encountered a hovering flattened sphere that accelerated northeast when approached.”
“Hall says Messmore and Sonner computed possible speeds from angular motion under assumed altitudes, ranging from 2,880 mph at treetop level to much higher values at greater altitude.”
“Hall argues that airline and military pilots are unusually experienced sky observers because their work requires repeated exposure to weather, aircraft, meteors, planets, and aviation hazards.”
“Hall notes that airline pilots were included in the CIRVIS vital-intelligence reporting system and cites 1954 meetings between airline representatives and MATS intelligence to speed reporting of unusual aerial objects.”
