For how far and wide the shrapnel went, it's amazing no one got killed or seriously injured. John The dream is dead, long live the dream.......😥

As for the cat like reflex comment... watch any slow mo explosion where people react. The debris has flown past them, far past them before they even start the reaction motion. Folks got lucky there. STOP POTATO HATE!

At 28:06 in this latest video SM talks about what happened and why. July 19th should be "Drive Like Rockford Day". R.I.P. Jimmie.

Max RPM rating for the blower was 65,000, when it self destructed, the recorded RPM was over 105,000 RPM. Oh! Look! it broke this other stuff too! Well DUH!

Flywheel bolts broke first, disconnecting engine from absorber/load. Engine immediately went to 12,000 RPM followed a millisecond or 2 later by the compressor detonation. Kevin

Kevin Yup thats how it looks to me that it all went down. I am not causing global warming, I am just trying to hold off a impending Ice Age!
