I, personally, am ignorant of how one would shoot a rocket by a planet in such a way to increase its speed.
I believe WGT may well have a case against NASA for stealing this idea from them. I'm pretty sure the idea to use a slingshot effect was first thought up by someone who had a couple of bad lip-outs on Kiawah. NASA has a time machine you know, had it for years. Some days they've had it for 25 years, some days they've had it for hundreds of years. You just never know.
