[Land-speed] Bloodhound

[Ray Buck]

  This makes for some other interesting (to me anyway) questions.

What about cars where the front wheels are in in-line configuration and 
would only leave one track?  Maybe this is where the money starts to get 
verbose.

Would this only be for FIA records?  How about SCTA?

And how about the John Burk liner that was described as having 
everything in front of the front in-line wheels?  (That one sounds extra 
scary to me.)
