Bright object over mt umunhum, vertically rises, saucer shaped object over san jose.Its barely night and Mt umunhum has a height of about 3400 feet, and I saw a bright object flying from the south toward/over Mt umunhum at about 1/2 distance higher than the moutnain or about 5500ft.The reason I noticed this was odd is because it did not fly on the standard flight paths used by military or commercial planes following over and into San Jose International Airport. The military craft fly over south-west San Jose at about 30-40000 feet, nightly every 15 minutes or so.I noticed this object-light was different so I ran in the house to get a camera.Within the 15 or 20 seconds of getting the camera and getting back outside, the object-light was gone...I could not believe it. I know spaceships exist, and have no doubt, so I started looking for it directly above the earth.Behold, about 30 to 40,000 feet I saw a saucer shaped object flying over ahead continuing toward San Francisco. I was facinated on how fast this object was able to vertically rise from about 5500 feet to 30-40,000 feet in about 15 to 20 seconds. Unfortunately I was not able to see the vertical rise while I was getting the camera.
