The first thing Cathy Cundill knew anything was wrong was when her mother-in-law suddenly grabbed her and dragged her towards the floor.
Both were on the top deck of the open-top sightseeing bus which collided with an overhanging tree branch in Mumbles, ripping off the partial roof at the front of the vehicle and dragging it along over the seats.
"My mother-in-law had grabbed me and pulled me down. I then realised what had happened. The impact happened so quickly, you kind of didn't realise it had happened until it happened," said Cathy.

She said that moments earlier her children had been sitting near the front of the bus and it was just luck that they had moved before the impact.
Emergency services rushed to Mumbles Road in Swansea at around 2.30pm on August 10 after the crash involving the Cymru Coaster bus, operated by First Cymru, which travels around Swansea giving people views of the city.
Witnesses said they heard children screaming following 'a sound like a car crash'.
A 12-year-old boy was airlifted to the University of Wales Hospital in Cardiff after the crash, and is understood to still be receiving treatment there. One other person was taken to hospital, but later released, while a number of other injured were treated at the scene. The Cymru Coaster service has since resumed on the same route following a risk-assessment.
Cathy had been on the bus with her children and her mother-in-law Pauline Cundill, with the group having a day out on their way to Verdi's.
Cathy explained: "We got on the bus at Swansea Bus Station, we just planned on going for a ride. We were going to get off at Bracelet Bay but we decided to get off at the area near Verdi's instead. We didn't know where to stop and just before the crash happened I pressed the stop button."
She said there was screaming and crying following the impact.
"I saw a little boy stuck underneath the roof. Me and the little boy's mum were crying. She had her feet and her hands underneath the roof trying to lift it up."
It was reported this week how scaffolder Jonathan Powell rushed onto the bus and helped free a child from beneath the roof. You can read the full story of that here.
"It was very, very bad, a lot of people were screaming. As we were getting out a lot of people were still upset and crying but it had calmed down a bit."
Cathy decided to step in and play her own role in helping to get passengers to safety.
The 49-year-old, of Fforestfach, explained: "I got everybody out through the window, I lifted everybody out. There was one man the other side grabbing the top half of their bodies and I was pushing them out by the legs. It looked a bit like Superman. I was last out of the bus as I was helping everyone."
Thankfully, she said she and her family did not sustain any injuries, and it was fate that things were not worse for her children.
She said: "I've had nothing, only a few scratches through the shattered glass. Apart from that I'm all fine. My children had been sitting in front and then they came to sit with us towards the middle. They asked to go back down the front but I told them to just stay where they were. It was very fortunate."
Mrs Cundill praised the paramedics who came to the aid of those in need.
"I take my hat off to them, they were amazing," she said.
"My heart also goes out to the bus driver."
