Formula Two has been rocked by frightening scenes at the Austrian Grand Prix, with one car flipping upside down onto another.

The F2 sprint race in Spielberg was suspended after just two laps because of a calamitous three-way crash at turn three.

In a bunched-up pack in the middle of the field, Sami Meguetounif jostled for position at the turn but ran out of room when he reached the apex, forcing him to clip the front right tyre of Red Bull junior Arvid Lindblad.

As that happened, Meguetounif’s car was shoved up onto the curb at the right side of the track, which flipped him back over the two cars to his left, including that of Luke Browning.

Browning remarkably had Meguetounif’s car directly on top of his, upside down, as it flew through the air, before it came to rest on the ground, again upside down.

The halo safety device almost certainly saved the lives of both drivers.

Against all odds, all three drivers walked away relatively unscathed while their cars were taken into pit lane and the race was paused for 30 minutes.

Joshua Durksen led a rolling start when the race eventually got back underway.

But Stewards had to intervene again just moments later when turn three claimed another victim.

Dino Beganovic was left stranded after contact with Oliver Goethe at the treacherous corner — which still had more carnage to spark.

Four cars were involved in an awful pile-up at the same corner in the final lap of the race when three drivers ran into the back of Amaury Cordeel, whose untimely spin left him sitting idle in the middle of the track.

Cordeel had been on track to finish fourth. After the crash, none of the four drivers finished with any points.

Campos Racing’s Pepe Marti survived his way to the chequered flag.
