Onboard footage following Logan Sargeant's horror Dutch Grand Prix practice crash shows the moment he didn't realise his car was on fire.
The Williams driver hit the wall hard after dropping two wheels onto the grass in a wet practice session at Zandvoort.
The impact against the barrier completely destroyed the right side of his Williams car, which stopped sideways across the track.

Practice was red-flagged for around 45 minutes after the incident, with the session resuming in time for the remaining cars to complete just one flying lap.
It was a heavy impact for Sargeant, who thankfully appeared to be fine and got out of his car.
But he didn't manage to extract himself from the Williams before a scary fire to the car's turbo power unit, with race engineer Gaetan Jago informing him of the danger on team radio.
Onboard footage from George Russell's Mercedes appears to show that Sargeant wasn't initially aware of the fire, which was put out by trackside marshals after he walked away.

The Brit frantically signalled to Sargeant to alert him of the fact, and he told his own race engineer Marcus Dudley: "He's on fire, he needs to jump out."

Sargeant is now likely to miss qualifying as a result of his crash, with Williams facing a race against time to rebuild his car for Sunday's race - although the team are cautiously optimistic that he may still be able to take part in qualifying.

Earlier in the 2024 season, Williams were faced with a far greater problem when Alex Albon suffered a heavy crash in practice for the Australian Grand Prix.
The team did not have a spare chassis in Melbourne, meaning Albon took over Sargeant's non-damaged car for the rest of the weekend.
And in Japan, a practice crash for Sargeant meant he had to take old parts as replacements, as the team didn't have a spare front or rear wing.
