Flash dime sized in sky lasting1 second followed by a boom then 5 min later something size of a semi.Glowing or fire submerg in water

I was looking up at the sky to the west about 1am aug 9 2023 and saw a quick 1 second white flash. If you were to hold a dime in outstretched in your fingers towards the sky thats how big it was, followed by am immediate bang right after. It didnt look to be caused by a meator as there was no shooting trail. So i decided to prop my phone up on hyperlapse pointing at that area of the sky. On hyperlapse 1 second in the video is equal to 15 seconds real time, so this 29 second video is actually just under 9 minutes real time. Upon watching the video playback at 14 seconds in something not in the sky caught my eye if you look mid center of the video u'll see something quickly flash. Zoom in and manually progress the video slowly from 13sec to 15sec and you see what is the puget sound something bright possibly hot or on fire appear above reflecting its glow off the water then submerg. The 1 second that it appears on video is actually 15 seconds real time that this object glided down into the water. The locatiin it went into water, I mapped the distance from me at about 3.3miles. Making whatever it was around the size of a semi with trailer. The only land near is Anderson Island home to the now abandoned prison. It was about 5 minutes after i saw the flash and bang before that object went in the water and a meteorite that size would of been visible whole way down and made a loud sound even from my viewpoint. Ive looked online and found nothing anywhere referencing this event ive also included a daytime photo next to the night shot of the object circled of the area it went down.
