North of England Reporter Hannah Miller hears from survivors as they speak out over the emergency services response on the night
While the sirens blared outside, those inside Manchester Arena when the bomb went off said on Thursday they felt "abandoned", as they described the medical response as "chaotic and without a plan".
Martin Hibbert and his then 14-year-old daughter Eve were the closest people to survive the attack. They were just six metres away when the bomb went off.
They had gone on a father-daughter night out, which ended in him watching Eve being covered with t-shirts and posters because people thought she was dead.
He told the inquiry in those hours he felt he had one job - to make sure she got out alive.
It was almost two hours before a paramedic came to save their lives.
Martin is now training to climb Mount Kilimanjaro - his latest charity challenge to raise money for others with spinal injuries after the attack left him paralysed from the waist down.
While he has used his experience to become a motivational speaker in a bid to inspire others, he rarely speaks about the impact on Eve and their wider friends and family.
Eve, who is now 18, suffered a significant brain injury in the attack.
She spent 10 months in hospital, with Martin revealing today she is thought to be the only person in the world to have survived such severe injuries.
She can now see, hear, talk and eat, and will be able to "inspire the world" when she is ready, her father said.
Martin fought for his testimony to be included in the inquiry, following what he described as a "catalogue of errors" in the response on the night.
He thanked a paramedic called Paul, who he has since learned ignored official instructions and took him to the closest hospital to the blast.
"It wasn't true that the emergency services were there immediately", Mr Hibbert said.
He believes that only by hearing the experiences of those who lived through the agonising wait for help will lessons be learned for the future.
