Military officials say a streak of light seen burning across the sky by people in three western states was debris from a Russian rocket re-entering the atmosphere.
U.S. Strategic Command spokeswoman Julie Ziegenhorn says the fireball seen over Arizona, Nevada and California in the Tuesday night sky was an SL-4 rocket body booster from Russia that was launched Monday.
Luke Air Force Base and the Arizona National Guard say they had no reports of any strange lights.
