On 21 June, less than two months after its first flight, the Racer demonstrator exceeded its level speed objective of 407 km/h (220 kts) by reaching 420 km/h (227 kts) in its initial configuration. In just seven flights and about nine hours of flight testing, almost all of the flight envelope has been opened.
