Can anyone help me explain what I saw in the sky tonight?

Hello all! First time poster here, but longtime lurker, and would love to know if someone has any explanation for what I saw in the sky tonight. I tried Googling, but didn’t find any answers that seemed close enough. I’ll try to describe it.

I was out walking my dog, and she stopped to sniff something very intently, so I decided to stop and let her sniff and my first instinct on a clear night is to look up and see if I can spot any satellites. So I’m kind of just peering around the night sky, and two fairly dim-looking “stars” (I don’t think they were stars, but that’s what I’ll call them) which were stationary at first, suddenly start moving, unnaturally fast (in my mind). They were moving way too fast to be satellites in my opinion, but I am not an expert. They were positioned right next to each other and moving in tandem, but they weren’t moving in a line like the Starlink satellites that I’ve seen video of; they were moving like they were attached to the wings of an aircraft, and I got the sense that there was *something* in between these “stars” that I couldn’t see because the craft itself was either as dark as the night sky or cloaked in some manner. I watched them move across the entire sky in about 3 seconds, and then they disappeared as suddenly as they started moving. I stood there a few moments and stared at the sky, wondering if they would reappear or not, but nothing else happened. I briefly wondered if it was a plane, but spotted a plane in the sky a similar distance away, and its lights were much brighter and flashing, and it was moving much slower. I could also hear the engines of the plane, and the “stars” made no sound that I could discern.

Are there any logical explanations for this sighting? Could it be military? It was so eerily quiet. I do live on the eastern shore of Maryland, so there are military bases and government headquarters nearby. It also would not have been noticeable to anyone on the ground unless they were looking directly at that spot in the sky like I was; they were very dim “stars.” Any explanations?
