Court shown video reconstruction of Gwyneth Paltrow ski collision

Watch the ski collision reconstruction video shown to the court

Gwyenth Paltrow’s version of events in the ski crash at the centre of a lawsuit is “consistent with the laws of physics,” a US court heard after being shown an animated reconstruction.

Biochemical engineer Dr Irving Scher disputed evidence from previous witnesses, claiming their analysis had been miscalculated and he could not get other scenarios “to work”.

Ms Paltrow has claimed that retired optometrist Terry Sanderson collided with her during the 2016 incident at the Deer Valley resort in Utah, and resulted in her losing “half a day of skiing” with her family.

Mr Sanderson has accused the actress of crashing into him, and says he sustained several broken ribs and severe head injuries.

Jurors were given a short physics lesson in court on Tuesday by Dr Scher, in which he wrote out several calculations and diagrams on a large board with a marker.

They were later shown an animation of Ms Paltrow’s version of events.

Dr Scher said calculations by Dr Richard Boehne, heard in court last week, had been “thrown off” by an incorrect velocity, and that corrected measurements meant Mr Sanderson’s injuries should have been “much worse”.

“Ms Paltrow’s version of events is consistent with the laws of physics in how people turn and rotate,” he said.

“Dr Boehne cannot say with any accuracy that Ms Paltrow landed on Mr Sanderson. His calculations are wrong.”

“I believe Ms Paltrow’s version is possible,” he said before agreeing with James Egan, representing the actress, that it is “likely” … “considering it is the only one that matches with the physics”.

In his evidence, Dr Boehne said Ms Paltrow instigating the crash is the “only scenario” that could have resulted in Mr Sanderson’s injuries and he had provided a “cushion” for the actress.

“Dr Boehne cannot say that Ms Paltrow’s version of events is impossible… it is the only version out of the two that matches with the laws of physics,” Dr Scher said.

Asked about evidence from another skier, Craig Ramon, who was present at the time of the incident and claimed Ms Paltrow caused the collision, Dr Scher added: “I couldn’t get it to work”.

He also noted that it would have taken very little force for Ms Paltrow’s skis to come off in the collision, but they stayed on.

“I know how bindings work, it’s just physics,” he said.

“If her skis stayed on I can’t see how she continued to move 10ft… if she was trapped underneath him.”

The court has already heard evidence from Ms Paltrow and Mr Sanderson.

Mr Sanderson said he had become a “self-imposed recluse” after the incident and had been advised never to ski again in case of further injury.

Ms Paltrow previously said she felt “very sorry” for Mr Sanderson but reiterated that she was not “at fault” for the crash.

The trial in Park City, Utah, continues.
