Interesting facts

Almost five times faster than the Concorde, capable of exceeding 100 km in altitude at more than Mach 10 and taking off from airports without a launch platform, the Aurora from Polaris went from seven demonstrators and 250 test flights to accelerate the race for reusable space planes.
