The Africa Aerospace and Defence (AAD) Expo at Waterkloof Air Force Base outside Pretoria never fails to produce eye-catching and innovative displays.
This year, aviation enthusiasts, including school children, saw what promises to be the world's largest helicopter made from beads.
A novel Guinness World Record Challenge has seen Denel and several other defence companies come together to build the world's largest beaded helicopter.
It is a full-sized replica of Denel's new rotary wing unmanned aerial vehicle (UAV), created with around 150 000 coloured glass beads.
The beads are slightly larger than the ones usually used to manufacture beaded artworks.
