UFO Sighting In Salt Lake City?

Is it a rocket? Is it a blimp? Is it a UFO?
A strange object seen in the skies above in Salt Lake City has residents scratching their heads.
What appears to be a huge air balloon was seen floating above the valley Wednesday morning.
The silver, rocket-shaped craft was sighted about 8 a.m. and floated about for several minutes before disappearing.
Salt Lake Air Traffic Control said they didn’t pick up the object on radar and had no knowledge of the craft.
They will be looking into the sighting to see if any air traffic rules were violated
