Description

nighttime sighting of a UFO that appeared to be massive based on motion parallax visual geometries to snap-triangulate its distance. likely miles out with the size of a thumbnail at arms length. Stadium or larger in size would be my guess. Craft was:
self illuminated ,
white,
ovoid ijn shape
slow steady clip
diagonol downward trajectory
emitting of a Velvety white (self luminous) vapor. Akin to the sublimation of frozen carbon dioxide to gas. with electric blue tinges at extremities.
disappeared within the moment it took me to look at the road while running on foot to get a better view.

Event occurred at Riggins, Idaho on a cool clear spring night. circa 1994-1995
