On 21 August 1974, the Hawk T1 prototype (XX154) took flight from Dunsfold, soaring to 20,000 ft in just 53 minutes and hitting speeds above 360 mph. Piloted by Duncan Simpson, the trials continued the next day—reaching 27,000 ft and nearly 500 mph. With minimal adjustments, the Hawk entered RAF service in just 27 months, offering exceptional handling and visibility. Today, it remains the iconic jet trainer of the Red Arrows, serving multiple air forces and evolving from advanced trainer to interceptor, including the modern T2 variant introduced in 2009.
