I usually look at dafont.com. I have a few that are close. One is called DymaxionScript and another is Hood Ornament. I also have Rocket Script. I got them all at dafont. I don't know if that helps, but I thought I'd share.
The actual logo looks like a slightly customized "Magneto Bold Extended" which is a commercial font. Mickster's suggestions will get you pretty close for freeware.
