A Bridgestone employee was seriously injured in the helicopter crash that killed three others and injured another last night at Magny-Cours, the Japanese company said.
The helicopter was leaving the circuit at 7:30 pm heading towards Castel Donzy. It is unclear what caused the crash.
"It is with great shock and sadness that Bridgestone informs all parties of a fatal helicopter crash involving a member of Bridgestone personnel," Bridgestone said.
"The Bridgestone employee and a relative survived the crash.
"Bridgestone wishes to express its sadness and concern at this difficult time."
The chief medical officer at the Nevers region added that the names of those involved in the crash are currently withheld by the police until the next of kin are informed of the tragedy.
