https://www.nicap.org/docs2/660323_cufos_greenwood.pdfanyone happen to know what the designation "TL-4786" or some similar combination of letters might be as an identifying marker on a military or experimental aircraft? The pilot had US Army Seargant chevrons on the sleeves and was wearing an air force mechanic's hat with bill turned up, if any of that context can help with the id. thanks a trillion if you help.
