March 20, 2016 stays a kind of days when Formulation 1 frightened us, but in addition demonstrated its steady progress in security and its willpower to all the time go additional. It was 10 years in the past, through the Australian Grand Prix, and a stunning crash sustained by Fernando Alonso continues to be vivid in some recollections.
On lap 17 of the race, whereas battling for nineteenth place on the wheel of an underperforming McLaren-Honda, the two-time world champion tried to overhaul Esteban Gutierrez across the outdoors of Flip 3 however struck the rear wheel of the Haas. He was instantly despatched in direction of the surface wall and, disadvantaged of any steering management, the automobile slid right into a patch of grass and gravel the place it dug into the bottom.
It then started to roll, earlier than coming to relaxation the other way up close to a tyre barrier. Alonso shortly climbed out of the wreckage unhurt. Though shaken, he was on his toes. However, he suffered a pneumothorax and damaged ribs, forcing him to overlook the next grand prix.
When this accident occurred, F1 was within the midst of looking for an answer to higher defend drivers’ heads. The halo had already been examined for a number of months, first launched by Ferrari throughout that yr’s winter testing and evaluated alongside one other machine, the Aeroscreen. Confronted with the tiny hole by means of which Alonso managed to extract himself from his McLaren, questions shortly arose, additionally permitting these against the halo to criticise the FIA.

The governing physique logically launched an investigation into the Spanish driver’s accident and, for the primary time, benefited from footage captured by the brand new ultra-high-speed cameras put in in F1 automobiles since 2015. These notably helped enhance understanding of the implications had the halo been current in such a scenario.
Staggering figures
Lower than three months later, the conclusions have been made public. First got here the staggering figures. The video recording, mixed with information offered by accelerometers, revealed the size of the impression.
In the mean time of contact with Gutierrez, Alonso was travelling at 313 km/h; when he hit the wall, the lateral deceleration impression was measured at 45G; then the same impression of 46G was recorded through the roll. For 0.9 seconds, the automobile was fully airborne and, when it landed, the rear skilled a longitudinal acceleration of 20G. As for the well-known high-speed digicam, it revealed that the motive force’s head struck the left facet of his headrest twice.
“What we need to perceive is the precise dynamics of the pinnacle, neck and shoulders in a crash with excessive g-forces, and the way they work together with different elements of the cockpit surroundings reminiscent of the pinnacle safety, the HANS, the harnesses and every thing which may be within the area across the driver,” defined Laurent Mekies in his report, then managing director of the FIA’s analysis institute, now crew principal at Purple Bull.
“This digicam permits us to higher perceive the precise forces skilled by the pinnacle throughout a given motion, the elongation of the neck, the way it interacts with the headrest, how the latter works and what we have to do for the subsequent technology of cockpits.”

Past this important side of cockpit security parts, the FIA then included the findings of its investigation into its broader analysis on driver head safety. The governing physique pushed its seek for solutions so far as doable. It even went as far as to simulate Alonso’s accident with the halo. The outcomes, revealed in early 2017, have been very encouraging and even satisfied a number of drivers once they have been introduced with them.
“We flipped one in all our chassis with a halo,” Mekies defined on the time. “We put Andy Mellor [FIA technical consultant] inside to evaluate the worst-case situation and requested him to get out, exactly in Fernando’s place. Extremely, he managed it,” Mekies smiled. “So, we really feel that on this case, the halo gives area for the motive force.”
This marked one other barrier being damaged within the FIA’s lengthy effort, decided to introduce the halo in F1 earlier than extending it extra extensively to different single-seater classes. Like this impediment, others step by step fell away, generally accompanied by philosophical debates that fuelled discussions.
In any case, by the winter of 2018, the brand new F1 automobiles have been certainly unveiled outfitted with the halo. Since then, the presence of this security machine has by no means been questioned once more. Simply ask Romain Grosjean, amongst others.
