VOICED : Dutch student team sets world land-speed

The video covers the Netherlands human-powered team's achievement of a new world land speed record, with Sebastian Bovair reaching over 83 miles per hour. The record was confirmed after a delay by Nevada officials. The event took place on a flat surface, ideal for such attempts. A tandem bike record attempt faced challenges, including a crash. Bovaird shared that success relies on both the bike's aerodynamics and the rider's condition. The team's project manager highlighted a key aerodynamic discovery that contributed to their success.
