Commuters ran for their lives as the flames from Ahmed Hassan's bucket bomb exploded sending a fireball racing down the carriage.
There were 93 people on the train with 23 suffering burns. One woman described discovering her hair was on fire, another how her tights had melted. A further 28 were injured in the crush as commuters tried to get off the District Line tube at Parson Green on September 15th last year.
Chris Wildish was on his usual morning commute.
" I was on my way to work, sitting on the train reading my book as I always do and I heard a thumping sound and out of the corner of my eye I saw the flame shooting up the side of the carriage and up into the ceiling. It happened and there was a pause and then a tidal wave of people running down the carriage and everything you've heard about a stampede is real. People will do what they need to do to get out of the way. People falling over, other stamping on them, people running along the seats."
In his defence Hassan told the court he was "certain" the device would burn rather than explode and he had never intended to kill or endanger anyone's life but the jury did not believe his version of events. Chris Widlish says the jury's verdict was correct.
"I don't believe he didn't aim to kill......It was an explosive device. How he could put that on a train and think it wasn't going to kill people? The second thing is the shrapnel. If you're only trying to scare people or make a statement don't put shrapnel in it because people are going to die".
Ahmed Hassan ordered some of the key chemical ingredients for his device on Amazon. The nails, screws and knives he used as shrapnel came from Asda and Aldi. He used a standard kitchen timer as the ignition switch and then placed the device in a plastic bucket.
Almost every stage of his journey from his home in Sunbury to the moment he planted the device on the tube, was captured on CCTV.
His arrest a day later in Dover was also captured on camera.
Ahmed Hassan arrived in Britain in October 2015 as a 16-year-old asylum seeker. His mother died when he was a youngster and he told immigration officials his father was killed in an allied forces missile attack.
The teenager was taken in by Barnardo's, and at one stage was hospitalised for depression. His immigration status was still under consideration at the time he planted the device.
Hassan has been remanded in custody and will be sentenced next week.
