Accident involving Red Arrows Hawk T Mk1 XX179 near Bournemouth

On 20 August 2011, the Royal Air Force Aerobatic Team (The Red Arrows) was performing at the Bournemouth Air Festival. After completing a successful display, the formation of nine Hawk T Mk1 aircraft returned to Bournemouth Airport for landing. During the "break-to-land"—a standard high-performance manoeuvre used to position aircraft for landing in quick succession—Hawk XX179, flown by Flight Lieutenant Jon Egging (Red 4), deviated from its intended flight path. The aircraft was observed to enter a progressively steepening descent before impacting the ground in open fields south of the airport perimeter.

The Service Inquiry (SI) concluded that the most likely cause of the accident was G-induced impairment, specifically Almost-Loss of Consciousness (A-LOC). During the break, the pilot was subjected to a peak of 6.3G. The inquiry found that Flt Lt Egging likely became semi-conscious or suffered from significantly reduced cognitive function due to the sudden onset of G-forces. This "grey-out" meant he was unable to maintain the aircraft's altitude or respond to radio warnings from other pilots in the formation. Evidence suggested he began to regain awareness approximately three seconds before impact, but he had insufficient height to recover the aircraft or eject.

The investigation delved into the systemic and organisational factors behind the crash. It noted that the specific manoeuvre, while routine, was being flown at a speed and G-loading that increased the risk of A-LOC. Furthermore, the inquiry identified that the team's training on G-awareness and "G-straining" manoeuvres had not sufficiently prepared pilots for the physiological effects of rapid G-onset in this specific flight profile.

By early 2026, the legacy of the XX179 inquiry is seen in the fundamental changes to Red Arrows display protocols. The "break" manoeuvre was redesigned to be flown at a lower speed and with less aggressive G-loading. Additionally, the RAF significantly enhanced G-awareness training across all fast-jet fleets, introducing more rigorous medical screening and simulator-based physiological training to mitigate the risks of G-induced loss of consciousness (G-LOC/A-LOC).
