March 2018 version: Chute deployment handles modified with auxiliary linkages? Looks very dangerous. Source: https://www.realrocketman.com/

March 2018 version of rocket: Main chute did not deploy. Main chute had a sling for horizontal decent. Hit nose first instead. He mentioned on this launch having automatic chute release. Deployment handle in more difficult push arrangement, rather than pull. Same fake licence plate...

I'm speculating his seat broke. https://www.youtube.com/watch?v=sZRmbxUt9TY

Three chutes (red) with deployment rockets directly aimed at passersby. I do not know what state of arm they might have been in during transport. Green is damage to skirt. Set off by pulling handle on end of wire cable. Solid rocket motors ignited by percussion primers. Insufficient slack in...

I was checking out Mike's parachutes in this video. https://www.youtube.com/watch?v=BFwoU2SZg_s It seems he had three chutes. Note how for his 3rd launch he used a converted dump truck. What is strange about this launch truck is the homemade licence plate. The plate number UCC 1-308 is used...

Living your dream should not be a euphemism for taking unnecessary and ill-informed risk. This stunt seems to have been underfunded. It seems his original interest was using steam rocket to jump over a "reasonable" distance. This morphed into claims he could reach the stratosphere when it got...

Not trying to make joke - launch on 02/22/2020, duration of flight exactly 20 seconds. There is a lot to learn here about human nature and the disregard of engineering realities. I wonder who was helping him? Were they really aware of the risk? His first rocket took 10 years to construct. How...

Re: Corpus Christi Harbor Bridge. Does anyone here know what kind of waiver or exemption allows children to be in construction yard? See photo gallery here: https://harborbridgeproject.com/gallery/

Re: Repairability When a girder fails, usually the entire girder is replaced as a repair. Since this bridge was designed as a single girder, the only practical form of repair is total replacement. Since the whole idea of the single girder was to lower cost, it should therefore not have been a...
