Yes, there was. The answer is that, unlike suborbital vehicles, no one is working on them, or funding them. I also answered the payload question, unless you're unable to multiply two numbers together. If that's the case, I'll do it for you (six passengers plus two crew at 200 lbs each, average, is sixteen hundred pounds), but I'm not sure why you want to flaunt both your lack of knowledge and lack of ability to do simple arithmetic.
If you will check my post #60 on this thread, you will see I did the math you asked for and a little bit more. Please think before you post. You are sounding more and more pathetic.
PS: Bert Rutan is not working on a non-passenger SOV so the development time will be much longer.
I just like to hear you thrashing about with no substance to your “facts”. Reality must be a foreign concept for you. Who is working/funding on the non-passenger SOV? Would you please answer that for me?
I’m surprised you didn’t bring up the Aurora approach. That is much further along and has much more promise of being a delivery system of the sulfur earlier and is already flying. Just thought I would help you out since valid meaningful research seems beyond you very limited abilities.
