PS: Bert Rutan is not working on a non-passenger SOV so the development time will be much longer.
I see you finally did figure out how to do the math.
Given the Nutty Professor’s estimate of 1,000,000 tons of Sulfur needed it will only require 1,250,000 flights.
Yes, unless they decide to build a bigger version for the mission. Building a ten-thousand pound vehicle would be trivial for suborbital.
I see in the propaganda for the tourist version they say they can maybe make 2 flights a day.
That's only because they don't see a bigger demand than that for tourist flights--it's no intrinsic limitation from a design standpoint. If there were a larger market, they'd just build a bigger fleet. These things aren't any larger than a business jet, and they use less propellant. There's no reason that one couldn't do thousands of flights a day, just as business jets do.
The numbers were run at this web site. The guy who did it is an aerospace professional. Your qualifications are...?
