This aircraft is my second supersonic aircraft built from scratch. To take off, activate full thrust, wait until the aircraft is going around 300mph, then pitch upwards. When at 1000ft or above, activate group 1. To land (this is important) if going 1100+mph, as soon as the island that you are landing at comes into view, brake, or 0% thrust, deactivate group 1, activate groups 2 & 4, and then 25% thrust. Once the two side jet engines stop producing exhaust jets, decativate group 4, to allow maneuvers to align with the runway. Once aligned with the runway, activate group 4 and gear. Once directly above the start of the runway, brake and activate group 3. Make sure you are no more than 750ft above the runway. AG1: Secondary engines. AG2: Parachutes. AG3: Parachutes. AG4: Gyroscope.
