therethat morning i was driving west bound on I-70 near Lambert International Airport. when i exit I-70 to get on I-170 north bound, to my left is the airport which had a regular commerical plane landing at this time. right above the airport there was a silver object shaped like a food cover that most hotels use. this object was ascending once i got fully focus on it. this was a clear sunny day with some clouds. i watched this thing actully disappear into a clear sky. further up was a commerical plane at a very high altitude with a smoke trail flying southwest across the sky. i really don't know what i saw. but i found it to be strange that 15min after i saw military frighters flying around and landing (which is normal because of Boeing). i'm not a UFO believer, but i saw what i saw.((NUFORC Note: Witness elects to remain totally anonymous. For another sighting over the same airport in July 1954, please see entry in the NUFORC database for that date. PD))
