'Air Force FM' - Defence Force Recruiting, Australia

The brief was to find the most skilled radio technicians for the air force. The idea was to build the radio before you hear the ad.

Only the best recruits were able to complete the task before tuning into the radio to hear the ad, which contained the special password to log on to the website.
