consider that we with all our expertise and that of the German rocket scientists, we still had years of failures
in our programs. its math/science/engineering/program management, and being able to learn from failure.
they also need for there to be freedom to bring bad news
to the attention of management.
MONK I think we need your Gary Cole photoshop here with him directing phone lines ROFL
Just heard that the US announced the food shipment would be “curtailed.”
Likely to be reintroduced in June...
Some things are just difficult. You can't simulate everything (such as the effects of vibration, thermal shock loads, timing issues on separation, etc.). The US had a couple of dozen failures in our early rocket program. Remember Vanguard?
The joke was that Vanguard was like a government worker: 'You can't fire it and you can't make it work.'
Confucius also say man who lose big rocket lose little rocket.
He is in really, REALLY, deep kimchee...
Vanguard got up, sat down
The reporter in the blue jacket is thinking, “If I laugh, they are going to kill me and BBQ my family. This is very hard, holding it in...”

———The US will send $250 million in food, hoping to change the attitude of the NK.————
Interesting comment upon which I can shed some real light.
I spoke last week with a man with an organization called Samaritan’s Purse. They have a program involving Shoe Boxes of stuff and I think food. This is the organization of Franklin Grahm and operates from their Charlotte facility
He told me they have a shipment for North Korea ready to go but it was put on hold by the US government because of the rocket. Now that the rocket is failed, one wonders if the rescinded permit will be reinstated?
LOL - good one.
A high-five and a “jinx!” I think my word was “dogmeat,” though.
A liquid fueled rocket is best described as a "controlled explosion". There is a very fine line between controlled and uncontrolled however. A missile is a very complex machine with thousands of parts. A failure of any one part can compromise it's flight. The more parts there are the more things that can go wrong. Modern missiles are designed with the absolute minimum of parts since any redundancy would increase weight and lead to more complexity, both undesirable traits. I am surprised that the North Koreans have not transitioned to solid fuel rockets as Iran has done. The difference being the elimination of much of the failure prone machinery used to move the fuel and oxidizer from storage tanks to the engine.
US missiles (except cruse missiles) whether land or underwater based, are all solid fueled. Solid fueled rockets are as dependable as a rifle cartridge, light the fire and it goes every time. The only advantage that liquid fuel has over solid is the ability to vary the thrust in flight which is not worth the complexity. If you want to shorten the range of a given solid fueled missile you could program the guidance system to track a steeper ballistic trajectory rather than vary the thrust.
