The operations director of Malton-based tofu brand The Tofoo Co suffered life-changing injuries and was flown immediately to Leeds General Infirmary by air ambulance.
Tests revealed that Mr Eastwood had broken his spine in four places, suffered internal bleeding and seriously damaged his bowels. He spent 21 days in the hospital and has endured four surgeries.
Although the other driver involved was driven to York Hospital, the extent of Mr Eastwood's blood loss meant his life would not have been saved if he had not been airlifted.
Now recovering and able to walk again, he has decided to raise funds for the Yorkshire Air Ambulance to thank them for their assistance and has registered to become a volunteer.
He plans to run eight miles from Wakefield to LGI later this year alongside 10 family members, friends and colleagues.
He said: “I had heard of Yorkshire Air Ambulance, but I had no idea that they are a charity. If it wasn’t for them, I would not have made it to the hospital in time by land ambulance due to massive internal bleeding. I’m really grateful for all they did and want to give back to them by doing all I can.”
