A series of parachute jumps were undertaken in association with a school fundraising event. Although the weather was breezy, it was considered suitable for jumping. Five jump flights had previously taken place, each with two tandems pairs and a single parachutist. The landings were generally about the touch down or Drop Zone (DZ) on the airfield. On the sixth jump flight, one tandem pair landed off the airfield. During the landing, they collided with a tracked mechanical digger, sustaining serious injuries to both parachutists.
