On thanksgiving day i was taking the bus to another part of the city to visit my family. on the way there i was staring out of the window looking at the water as we drove down a bridge highway. there is an airport very close by so i am used to seeing a lot of airplanes flying low. i noticed something very bright and low flying in the sky. i had the feeling that this wasn't an airplane and it seemed to be hovering still and not moving. as i tried to figure out what i was looking at i saw that it seemed to either be emitting very bright light or was reflecting it, not like an airplane or car light but like its entire surface area was emitting it. i could see that it was metallic and i was trying to figure out if it was actually hovering still or if it was an illusion from the bus moving. as i was trying to figure this out it suddenly vanished. i have seen ufos from very far away in the past and the way that they vanish is very distinctive. it is like when you flip a light switch and the bulb slowly dims out, while also going upwards into the sky.
