As the drivers lined up on the grid for the start of the Bahrain GP no one could have imagined what was about to happen, within seconds after getting away.
However in that split second move Grosjean did not it appear to anticpate Daniil Kvyat being alongside him.
A minor collision with Kvyat, turned out to be one of the biggest and scariest crashes we have seen in F1 in a number of years.
Grosjean then careered toward the barriers at 160mph, hitting them at a slight angle, ripping the car in half as the 110kg of fuel instantly ignited resulting in an explosion made more dramatic (but no less serious) at the night time race.
As Grosjean was trapped in the remaining front end of his car, which was wedged through the torn barriers and engulfed in flames, dramatic scenes were shown of Grosjean miraculously escaping and leaping out of the car.
Aided by the heroic medics that tail the cars on a race start, Alan van der Merwer doused both Grosjean and the Medical Car driver, Dr Ian Roberts with fire retardant as they ran for safety.
There is no doubt, Grosjean has had one of the luckiest escapes in Formula One for a long long time. Such was the severity of the impact and damage as the car tore through the barrier.
The Halo system no doubt played a significant part in the safety of Grosjean and likely saved his life.
It was later confirmed Grosjean had received burns to his ankles and wrists, he will be reflecting on how incredibly lucky he was.
Lewis Hamilton took to social media in the stoppage to post an statement around the work that has gone in to F1 in recent years to help with the safety:
“I’m so grateful Romain is safe.
“Wow… the risk we take is no joke, for those of you out there that forget that we put our life on the line for this sport and for what we love to do.
“Thankful to the FIA for the massive strides we’ve taken for Romain to walk away from that safely.”
Immediately after the accident, Haas team principal Guenther Steiner told Sky Sports:
“[Grosjean] is doing OK. He has light burns on hands and ankles.
“Obviously he is shaking and going through all the checks but he’s fine.”
The race eventually restarted where within a few corners of an obvious nervy restart, we saw Kvyat involved in yet another major incident. This time flipping the Racing Point of Lance Stroll upside down.
Stroll crawled out from under the car unharmed, again the car technology of the monocoque life saving cell doing its job again.
The medical car team have never been so busy in such a short space of time but everyone was thankful they were there when needed.
