July 31, 1948 — Indianapolis, IN
8:25 a.m. Mr. and Mrs. Vernon Swigert of south-central Indianapolis, Indiana, see a cymbal-shaped or domed-disc object to the west of their home. It is about 20 feet across, 6–8 feet thick, white without any shine but shadowing on upper right. It flies straight and level from horizon to horizon, west to east heading 90°. They estimate its altitude as 2,000 feet covering a distance of 5 miles in 10 seconds. It shimmers in the sun as if spinning, is silent, and has no trail. [Eberhart]
