The post that triggered my response claimed:
Ill say it again - SpaceX rockets havent crashed., which you quoted in your first post within this thread, commenting that "It seems there are a few here highly disappointment about that", to which I responded.
See? No qualifications about "mission" launches.
I responded by (correctly) pointing out a SpaceX rocket crash which directly contradicts his assertion.
Your further assertions about SpaceX not having had a failure of a mission launch came after that. So your "you deny this" statement is completely inapt. I have never made any such denial. It's not cool to try and put words into someone else's mouth that they have not spoken or written. Maybe you are thinking of something that you wrote to somebody else on a different thread.
Do you have any idea what a test is and why they test these vehicles prior to mission launches?
That question is completely unhinged from reality. You can not possibly have deduced that from anything that I wrote, rather you are conducting an imaginary argument with a strawman that you have constructed out of nothingness.
My direct experience with actual spacecraft is somewhat limited, having only worked on the construction of one satellite which was launched into low Earth orbit from Vandenburg AFB back in 1978, but with plenty of other engineering experience, I certainly have an idea of "what a test is and why they test these vehicles prior to mission launches". So your entire line of argument is seriously misplaced.
But I suppose that you could simply be arguing in your spare time.
OMG, a test launch vehicle failed?
You should get this in to breaking news zippo...
