The fact that all the major governments involved, NK included, are not saying anything about the possibility of the missile being shot down speaks volumes. I wonder whether the remnants of the rocket have already been recovered from the ocean floor and by whom. If it was indeed "disabled" in flight, it would be best to get a hold of it so there's no evidence of "a mysterious blast hole" in the rocket's body somewhere. Now that would be an interesting front page image to see (possibly with very bad repercussions).
The US need to keep shooting them down with the ABL, as they probably did in this instance. Don't kid yourselves - this is 1950's technology, not rocket science, in terms of getting it right in this day and age - kids are launching rockets in the desert that hit the edge of space.
The idea of not having any kind of thrust governor via the turbopump sounds ludicrous, which also means the claims of a lack of a throttle is also silly propaganda. They are disadvantaged, not stupid.
When the space shuttle Challenger exploded in 1986, there was talk about bringing back the Saturn V for use as "the heavy lifter". One of the big issues with that was much of the tooling had been destroyed (on purpose), so it would have been like starting over from scratch. After all, it was only our tax dollars that paid for it all to begin with. Why not pay for it all again?
I remember in the movie "The Right Stuff", John Glenn was freaking out over those vibrations. I thought his ship was just passing through the transonic range, but it must've been Max Q.
It is a shame that the populous are not able or willing to remove their miss-guided leaders. I wonder how long will their patience last, and realize that thier economy can withstand such waste. Would it have been cheaper to paid another country China, or perhaps even Rusia. To luch that satelite for them, if such was the REAL intent.
I was relieved when the rocket launch failed to achieve orbit but saddened by the cost in money and to the people of North Korea. The estimated billion dollar price tag could have gone a long way to fixing infrastructure, improving life for all the N Koreans and was not a needed effort. I am sure that leaders of countries have different values and goals than mine so maybe this made sense to them, but I am at a loss to understand.
Note to fellow space enthusiasts: I expect to be near the end of the runway at Dulles International Airport on Tuesday (April 17) when the Smithsonian Air & Space Museum facility at Dulles, the Udvar-Hazy Center, takes possession of Shuttle Discovery. It's unclear whether I would be able to see Discovery and its 747 carrier during its final victory lap around Washington, DC, so the end of the runway is the next best place since the 747 carrier has to land sooner or later.
You are correct, kinnar. Multistage rockets are the ultimate systems integration problem. The NK and Iranian rocketeers should have known that their third stage was take the brunt of the resonance associated with entry into the period of maximum dynamic pressure (Max Q). The fact that their rocket couldn't withstand these vibrations indicates they are a long way from launching a ballistic missile.
