On lap 5, Burgmann's Holden VK Commodore SS Group A and the privateer Jaguar XJS of his friend Garry Willmington were neck and neck over the notorious second hump on Conrod Straight at approximately 260 kmph when the front of the Commodore got airborne (as cars did coming over the hump at that speed, more so for cars on the right hand side or outside part of the track which is where Burgmann was).
