Let's not forget the famous "Grand Tetons Fireball" of August 1972. That
object actually entered the upper layers of the Earth's atmosphere and then
skipped back out into space (like a flat stone skipping across a pond). This
object was seen by many in broad daylight and there was even a 8mm. film of
the object skirting above the Tetons. Some suggest that the weight of this
object was in the thousands of tons (!) and its brightness was estimated by
reliable eyewitnesses as somewhere between -19 and -25.
