I witnessed about 3-4 Co2 rockets in the late 80s. But this was back before vents were added to pinvalves.
In all cases, someone accidentally crossthreaded the co2 tank. One case that I remember very well, someone had crossthreaded the 7oz onto an SMG60, and could not remove it. SO he had a friend hold the gun, while he turned it as hard as he could.......... BANG! The 7oz blasts away, bounces off the house, hits a van, the flies away about 300 feet.
Someone in 1989 was hit in the face by a Co2 rocket, and thats when the industry started adding the vent. That worked perfectly throughout the 90s.
The unfortunate death 3 years ago resulted from a threadlocked Co2 tank that had been removed in order to install an anti-siphon, then reinstalled. The user did not realize the threadlock had clogged the valve, and did not torque the valve properly.
As for burst-discs, in the 80s, and 90s, most were rated for 1800psi. I've seen probobly hundreds blow. These days, they are now rated mostly for 3000psi. I've never seen one of those blow.
