3 craft in formation

At 8:02 PM on Monday July 24th 2023 while at my son's Little League baseball game, I noticed, initially 2 oddly shaped objects flying overhead from the south, the objects appeared over the tree line (for a moment I thought the objects were powered parachute type ultra-light aircraft however, I quickly realized they were moving too fast and maneuvering oddly), they were dark gray or black, they had definitive lines of structure to them. One appeared to be an inverted pyramid, or upside-down top, this object looked as though it were tumbling forward, then would rotate / spin, the next object (in trail) appeared cube/diamond like, with curved edges so that when rotated at times would appear to be almost spherical, exhibiting similar flight characteristics. At this point in time another parent and I made eye contact, she said "tell me I'm not the only one seeing this", (2 other parents also witnessed this event and all were perplexed). At this time the third object came into view, further to the west, appearing to be higher in altitude and moving faster. This object appeared to be similar to object #2, it gained on the first 2 objects and then held in a loose formation, the formation was somewhat similar to an isosceles triangle. I was able to get the attached pictures. Weather at the time at nearby Bradley International Airport is included in the attached screenshot of the ATIS information that was current at the time of the sighting. The fields this sighting occurred at are quite large, the area is flat with a good field of view, these objects transited the visible sky from roughly south to north within 45-60 seconds. There was no noise, no contrails, no lights of any kind. According to the attached screenshot of flightradar24 there were no aircraft correlating to the location of these objects or in their direction they were traveling (at least none utilizing a transponder). Initial report to NUFORC was made via phone shortly after sighting occurred.
