Last night around 9:15 , I happened to look out my window .I'm on the 6 floor and have a perfect view of downtown Knoxville and the river . Coming up the river from west to east was what i first thought was a plane . It had strobing lights on both ends and a bright light in the center . As it passed over the building , it had no tail section and was completly silent . The altitude was probably around 200 feet or less . And its length was somewhere between 50 and 75 feet acrost , between the strobing lights . The total time of viewing it was maybe 6 secounds . When i first spotted it , it was about a half to three quarters of a mile away . The secound thing i saw was a white ball of light around 10 pm . About 30 degress above the horizion . Traveling north to south , it was about 1/8 of an inch in diamater . And really moving speed wise it went from right to left in about a secound or two . I dont have any sat trak programs anymore so maybe it was a satilight . The distance from me to the object is unknown . I sure would like to know if anyone else saw these objects last night .
