A meteorologist with United Air Lines observed a bright silvery object moving at high speed and altitude over Downers Grove, Illinois on July 4, 1950, which he confirmed was not an aircraft or natural phenomenon.

at 9:38 PM on July 4, 1950, he observed a large, bright, silvery object moving at an approximate altitude of 10,000 feet, in a north, north-westerly direction over Downers Grove. Mr. STENSIG said that his wife also observed this object. He stated that he estimated the speed of the object at 700 to 800 miles by comparing its rate of movement with that of commercial airplanes.
