The system was used officially for the first time.

AMA used two independent systems plus three manual timekeepers. The organizers decided that if the electronic system failed, the competitor should have a reflight, and the manual times should only be used for verification. This was approved by the Team Managers' Meeting before the contest. The success rate was 100%, and no reflight was called. Normally the times of the two systems differed just in the fourth decimal.
The system was operated by Bob Fogg.
