was meant to get off the ground (probably not, no nose cone for atmosphere exit/entry). I suggest the pressure regulators mainly based upon the fact that there doesn't seem to be an uniform buildup of propellant (to propel the craft upwards out of the atmosphere), that is, it seems on/off, not a steady buildup).

Just a guess...kind of fun to do.

Another guess...fuel mixture include hydrogen too? Based upon how quickly flames died down after the initial grand finale of the explosion (that is, nothing like gasoline was used, otherwise, it would (the flames) would last longer and hotter?

The engines were supposed to ignite, which they did, and generate thrust, which they did as evidenced by the dust and grit they kicked up. Then they were supposed to be shut down until the next test. The rocket had passed ground tests before this one.

It looked like something ruptured or popped open, spilling fuel and liquid oxygen after the engines were shut down. Putting it all together is going to be difficult, since most of it isn't there any more.

This is why they call it rocket science and why most of us don't do it.

I don't know what they're using for ground tests beyond liquid oxygen.

What I learn from this is why are we wasting money on these science toys while our people are going hungry.

Is that this will keep the government R&D subsidy money flowing that Elon Musk obviously values far more than the lives of his own employees. https://www.democraticunderground.com/100213428849
