If they are actually needed, I would be happy to do so.

For this rocket > there is a very sudden jump; before and afterwards the semi Do you mean "For this payload"? I'm lost trying to follow your point. Cheers.

John Dobson: "No, this is part of a study you are doing." (If anyone has the exact quotes and circumstances of this exchange, I'd love to see them. I think it might have been in the first episode of "The Astronomers".)
