A New Zealand-built rocket has shattered an altitude record after reaching speeds in excess of 2000 km an hour.
The small supersonic rocket was built by University of Canterbury students and launched near Tekapo last month. It accelerated so quickly that it broke the sound barrier only 70m above ground.
GPS data confirmed the rocket reached altitudes above 4889m, which broke the world record for the highest ever flight for an I-class rocket.
University of Canterbury students prepare the rocket.
