Massa immediately lost consciousness and was promptly flown to hospital, where he was treated for nine days - two of which were in an induced coma.
The Ferrari star would miss the remainder of the 2009 season as he underwent plastic surgery to restore the area of his skull that had been hit by the spring.

Massa returned in 2010 and competed in F1 until 2017 but never won another race after the accident, with the press criticising the 11-time race winner.
"Nobody ever told me I wasn't the same,” Massa said to Motorsport.com. “Of course I was criticised a lot in the press, because after my accident I didn't win another race in F1. But I came close several times.
"Unfortunately, I was denied victory in Germany, in the race that took place exactly one year after my accident, on 25 July 2010 [when his team ordered him to hand Fernando Alonso a victory].
“It was one of the saddest days of my life. After that, I lived a different period, because I no longer had a competitive car to fight for victories as before."
