A UAP- flying object that looks like a white color teardrop with a trail when moving fast. And no trail at some points of it's maneuver

On the 5th of April, 2022. At approximately 755pm, my daughter and son called for me about a shooting star in the sky. But to my amazement it was a flying white object that was flying horizontal from north to south, west and then immediately downward at a 75 degree angle or so. At about 300 to 500 feet agl, it disappeared from our view. There was no sound, or flash or splash that we could see from Lummi Island over looking Orcas island, Wa.
