Driving South on HWY 55, a brightly lit, very large object, passed above me at the intersection of Vision Dr.

On October 30, 2021, at approximately 7pm, I was driving south on HWY 55 toward Vision Dr. A (seemingly) huge, well lit object flew above me slowly. My first thought, due to the proximity of RDU airport, this was a 747, or some other very large aircraft either landing or crashing. I realized this was not the case, due to the object making no sound. I turned and drove up Vision Dr., while watching the object continue in a south easterly direction, close to downtown Apex. As I watched, the object changed direction, shifting north. The object did not bank, but merely shifted North while remaining horizontal. Very bizarre.
When I got home, I called the Apex police department, asking about any known low flying aircraft in the area. Apex was celebrating an Oktoberfest festival that evening, and I thought maybe it could be related, formation night flying or some other “show”. Their answer was no, no scheduled traffic.
This week (Thanksgiving) I found a commercial aviation radar app that has flight histories and whatnot (Flightradar24). There were no commercial or civilian flights recorded at that time on October 30, where I was driving. For this reason, I’m making the report.
In conclusion, the object was very large, flying low, slow and without sound. I saw no details of the airframe or other structure, due to the brightness of the lights. The lights were arranged in a “4” square pattern (which I reasoned maybe what 4 light aircraft flying in close formation would look like). All I remember is red and white, with 2-4 very bright white strobes. As another report on this same evening stated, this was a very busy highway and time of evening, with lots of traffic. I’m likely not the only witness.
