The Spec Focus Advisory Board and NASA has approved the 2008 rules. We’re very pleased with the changes that were made. There was not one single rule that was posted online or emailed to use, that we did not go through. Not all of them were approved by the board and some where not approved by NASA. Ford also provided much input on engine and other performance related questions.
