Tram crash survivor's search for friend in wreck
He kept asking: "Where's Dane? Where's Dane?"
"But all I could see was Dane's boot where he had been sitting," he added.
Paying tribute to his school friend, he said: "Dane was a genuine lad, did nobody any harm, really, no one deserves this to happen to them."
Mr Dale said he had been having flashbacks since the accident.
He said: "On the night of the crash I kept seeing the accident over and over again and couldn't sleep without the light on."

The 42-year-old driver of the tram was arrested on suspicion of manslaughter and questioned amid suggestions the tram failed to brake as it took a corner at speed.
On Thursday, he was released on police bail until May.
The vehicle was travelling at a "significantly higher speed than is permitted," investigators said. They are looking into whether the driver fell asleep.
Friends of Mr Chinnery, who is believed to be a Crystal Palace fan, posted tributes on social media.
Tom Curtis wrote on Twitter: "RIP Mate taken too soon."
Forensics teams are expected to continue working at the site until at least Thursday evening and identifying the dead may be a "complex and lengthy process", British Transport Police said.
The tram was travelling from New Addington to Wimbledon via Croydon when the accident happened at 6.10am.
Eyewitnesses described scenes in the wake of the crash as "total carnage" after the two-carriage tram tipped over in heavy rain next to an underpass.

Survivors said they recalled the tram failing to brake in the usual place when it came to a bend after speeding up.
Royal Navy veteran and father-of-seven Kevin Snow, 57, from Barnsley, South Yorkshire, was on his way to work in central London when the tram overturned.
He said: "Usually as you come out the tunnel you feel the brakes, but I didn't seem to at all. I thought, he should be braking in a minute.
"The next thing I knew we were on our side. Everyone was screaming and shouting, a lot of people were injured - lots couldn't move."
He said the tram slid for between eight and 10 seconds before coming to a halt.
Martin Bamford, 30, from Croydon, said he recalled the tram "speeding up" and added: "Everyone just literally went flying."
Speaking outside Croydon University Hospital, where he is being treated for fractured or broken ribs, he said people were screaming and there was "blood everywhere".
He said: "There was a woman that was on top of me ...I don't think she made it at all. She wasn't responsive. There was blood everywhere."
