Titan IV

The Titan IV was a family of heavy-lift space launch vehicles used by the U.S. Air Force from 1989 to 2005. It was primarily used to carry classified military and intelligence payloads into orbit. The massive exhaust plumes, staging events, and atmospheric phenomena generated by Titan IV launches were highly visible over large areas.

Missile and rocket launches, particularly heavy-lift vehicles like the Titan IV, are a frequent source of spectacular, wide-area UAP misidentifications.
