Switch the parking brake on then off after engine startup procedure to start the engines.
S73 is an remake of my 4 year old sonmen concorde, its better in every way and noticeably safer.
The S73 is fitted with 4 afterburners that can run at 195 RPS to make the airplane be able to cruise at mach 1.35 at 21-23.5KM altitude.
It can fly for around ~16 minutes at full afterburners but couple of hours on low altitude cruise, but this will always be your own choice.
Full climate & Pressure control for both the cockpit and cabin.
