Some people are working on cars that will go 800 or even 1000 miles per hour on the flat desert of Nevada.
The rules are simple. Clock the racer through a measured mile, turn around and do it again, then average the two speeds. Mr. Shadle said Eagle would need 11 miles for each run: a mile to warm up to 250 miles per hour; four miles to light off the afterburner and get up to record speed; a mile in the speed trap; and five miles to stop. The vehicle must have at least four wheels - two of them steerable -- and be back at the original start line within 60 minutes. And that's it.
