wiki: "The Minotaur I Rocket is an American solid fuel rocket designed to launch small satellites. It is built by Orbital Sciences Corporation and uses decommissioned Minuteman 2 solid rocket motors in its first and second stages, combined with Pegasus-based third and fourth stages."
Ahaha, rad - I've been on base for a few Titan IV launches - and the trippiest part is when the rocket is pointing directly away from you, as it makes this huge 4 pointed starburst that messes with your eyes. Dawn and evening launches are the best.
