Key Takeaways:

Dawn Aerospace's Mk-II Aurora demonstrator recently became the first civil aircraft to break the sound barrier (Mach 1.1) since Concorde's retirement over two decades ago.
The Mk-II Aurora also set a record for climb rate, reaching 20 kilometers (66,000 feet) in under two minutes and ascending to a peak altitude of 82,500 feet.
The company aims to be the first to fly an aircraft to the edge of space twice in one day and is expanding into "Dawn Hypersonics" to advance commercial Mach 5+ flight.

In 2003, British Airways and Air France retired Concorde—history’s only successful supersonic airliner. More than two decades later, a civil aircraft has broken the sound barrier once again.

Dawn Aerospace, the developer of what it describes as a rocket-powered spaceplane, on Tuesday announced it flew its Mk-II Aurora demonstrator faster than the speed of sound during a test mission last week. The New Zealand-based manufacturer is gunning to be the first to fly an aircraft to the edge of space—about 62 miles above the Earth—twice in one day.
