An Idaho witness in Ada County reported watching and photographing a "massive bell-shaped object hovering in the sky" about 8:15 a.m. on May 1, 2014, according to testimony in Case 55952 from the Mutual UFO Network (MUFON) witness reporting database.
The witness was driving westbound along Chinden Boulevard when the object was noticed hovering in the northwest sky.
"It just stayed there," the witness stated. "In scale, it appeared to be larger than a hot air balloon. I tried asking others about the sighting. They just guessed it may have been a hot air balloon."
"The object was in the sky for five minutes that I saw and then it descended behind the tree line."
