Dyson engineers build flying machines - Challenge Dyson 2013: Airborne. Dyson engineers are problem solvers and when they’re not working on new Dyson technology, they occasionally take on other engineering challenges after hours. The latest challenge was to build a machine that could fly through an obstacle course built from spare Dyson parts.

More than 100 Dyson engineers entered in both the UK and South-East Asia to compete. Balloons, planes, helicopters and several machines that defied description took to the air. Here are the results. Source
