Hi Kelly,

After having stared at it for half an hour I typed that relativisitic rocket
equation. Now I know why I couldn't believe its simplicity.
This morning I still was thinking about it and suddenly I knew what I had
done wrong, well not wrong, but the formula is to no use for you, since it
only takes into account the relativistic exhaust speed and not the
relativistic ship (Vend) speed. Since in your calculations Vexh is hardly
relativistic the formula is completely useless.
To derive the right equation, would take a while, maybe Rex has it by hand?

CU, Timothy
