Astonishingly, he suffered only minor cuts and scratches in the freak accident, despite the combined speed of impact between car and bird being over 100mph.
"One minute I was sat in the car chatting and the next I saw this huge bird plummeting from the sky," said 25 yearold Mr Ranyard, an IT manager from Keighley, West Yorkshire.
"I just froze as I saw it hurtling towards me. It came at me in slow motion like it had been projected straight at me. <a href="http://www.gooseparkas.top/" target="_blank">Canada Goose sale</a> I didn't shout out or put my hands up to protect my face. I just closed my eyes and braced myself.
"I half expected it to bounce off the car bonnet but then all of a sudden I heard a loud smash and felt a massive slap in the face which knocked my head back. I opened my eyes and was covered head to toe in blood, feathers and glass."
Mr Ranyard was being taken home from a work meeting in Bath by his boss Tony Deakin, 64, who drives an S registered Skoda Fabia.
They were on the M5 near West Bromwich when the goose which the pair believe must have been shot down by a farmer ended up dead on the back seat.
Mr Deakin managed to keep control of the car despite the heavy traffic and drove to a nearby hospital where his colleague was treated for shock. "I didn't see it coming at all," admitted Mr Deakin, a father of four from Collingham, West Yorkshire.
"Suddenly Martyn was covered in blood. I asked him if he was all right but he wasn't able to speak. He just kept screaming. All I could see was blood all over and didn't know whether it was the bird's or his."
Mr Ranyard, who practises hypnosis, said he must have placed himself in a trance after the bird left him in a flap.
"I can't remember consciously hypnotising myself but I must have done it automatically. It certainly worked, although I'm not sure what Tony must have been thinking. He probably thought I had lost the plot."
After Mr Ranyard was given the all clear to leave hospital, he refused to get back in the car and took a train home while Mr Deakin, who was not covered by his recovery policy, drove the 120 miles home with only half a windscreen.
He said: "It took me nearly four hours because I could only drive at about 45mph.
"It was absolutely freezing but I was just glad it wasn't raining."
Mr Ranyard has since been back in a car but admits he is constantly on the lookout for low flying birds.
