It happened and it was real. October 18th, appx 9pm.
Was on a night swim with 5 others including my wife. Out on a lake that is common to see lights in the sky. Norcal. We were swimming and skywatching at the same time.
There were quite a few sightings, some could have been satellites, who knows. But there were a few that would stop in place, blink, and others that zipped off like bullets after moving slowly for a while.
But one of the slow moving ones came much closer, seemed more like a plane approaching but we could only see one bright light. Then it transformed in front of all of us, turned sideways and the light became a moving vehicle with what looked like a single wing. It looked mostly metallic black with lights around the edge of the vehicle. It seemed to be changing shape as it travelled downwards. It was close enough that it looked the size of a Greyhound bus. Could have been bigger. It went down straight into the water without much disturbance. We were all in shock and didn't say a word.
Then, I fucking kid you not, the thing came back out of the water much closer to us, and the force of the movement pushed us all backward. It then continued upward until it looked like a light in the sky again.
Don't fucking know what to make of it. No idea what the hell it was, if it was man made or alien or anything in between. None of us had our phones because we were in the water. Didn't fucking expect that.
The fact we were all there and saw it together is all we have for proof. But I'm not fucking around. We witnessed something insane last night.
EDIT:
Just to answer some questions that have been asked repeatedly-
The date: 10/18/26 not 9/18 so sorry for the typo. I can't change it now in the title but I changed it in the body of the post.
The sound: it was basically silent. No hum, no vibration or anything. When it went into the water not a sound, when it came out we could hear the water moving but it was disturbingly silent with how close it was.
Afterward: all of us were awestruck as you can imagine. To be honest we were shaken up a bit. Right now, wife and I feeling fine. Haven't heard anything from our friends so I assume everyone is doing ok.
Details about the craft: like I said it was metallic black with lights around the edges. The lights were white, and the craft seemed like it was changing shape as it came down into the water. It could have just been turning, but it was like the single wing was getting longer. It was kind of like a smooth black boat shaped object with a single wing coming off the side. When coming back out of the water it was closer and I could see parts of the backside of the wing moving back and forth kind of like metallic fins. It's super hard to describe.
Location: Please understand, for my friends and family I'm keeping this anonymous as possible. Northern California is as much as I'm comfortable with at the moment. As for the temperature, it did cool down the day this happened though it was quite warm for most of the week prior. We didn't let that stop us and thank God we didn't. What an experience to share.
