As with every other S&S tower, Star Blaster got seatbelts. They're pretty awkward to fasten because of the minimal clearance between the arm rest and they slowed down loading a good deal.
Unfortunately Star Blaster wasn't running well. The launches were very weak and the ride was crawling by the time it reached the top of the tower. The result was barely any airtime. The seatbelts had enough give so the lack of air wasn't their fault.
