➀ In 2009, entrepreneur Richard Nobel was building a car designed to travel at 1,000mph, known as Bloodhound; ➁ The car uses a Menard V12 racing engine as a pump for a hybrid rocket engine and a Eurojet EJ200 turbofan for thrust; ➂ Stability is the main challenge for Bloodhound, with active aerodynamics and control systems designed to maintain contact with the ground without ploughing into it; ➃ The car's control system includes distributed multiprocessor systems and failsafe control mechanisms.
