“I would estimate the unidentified flying object was anywhere from 50,000 to 100,000 feet in altitude because I could easily see that passenger jets flew under it.”

October 27, 2012 Virgie, Kentucky - Major jet streams on Earth are upper atmosphere winds that blow west to east. The Northern Hemisphere has both polar and subtropical jet streams. Polar jets are stronger and flow at 23,000 to 39,000 feet above sea level (7-12 km). Subtropical jets are somewhat weaker at about 33,000 to 52,000 feet (10-16 km). That altitude is higher than normal airliner traffic. Passenger airliners fly around 32,000 to 40,000 feet.
