At 1047pm on 7/16/20 i was walking on my normal night walk and saw something i've never seen before and assume were multiple b-21's test flighting from wright-patt airforce base. i spotted a starlike ufo increasing and decreasing it's brightness from very bright to invisible every 3 seconds. traveling from west to northeast over vandalia/tipp city/troy, ohio in a straight steady speed line 25 degrees from due north horizon. while observing a single white flash caught my eye in the western sky miles and miles away from the ufo i was watching. the ufo shortly after began more eratic pulsating light and flashes from white to gold to yellow some extremely bright. approached a patch on the horizon of medium dark clouds and all of a sudden at 1052pm as it dimmed to invisible, two inches at arm length in the sky behind the ufo shot a beam/trail of yellow/gold light at light speed probably from the earlier 2nd craft. ufo never appeared lit again. later on the walk i saw two satilite starlike ufo's out of the eastern sky 50 degrees up from horizon moving at each other, one two inches at arm length higher than the other and they passed each other. 10-15 min earlier i saw a single satilite bright yellow starlike moving in the western sky south to north and it quickly dimmed to barely visible white. 20-30 min later i saw a single satilite moving in the eastern sky south to north stayed steady yellow. multiple airplanes flew over 30 seconds to a minute apart with parallel flight paths from ne to sw at 1120-1130pm flashing white on right wing to red on bottom/middle identical to each other. saw lots of cool strobe white and yellow tail lights.
