David Bottomley, 53, and his apprentice son Clayton, 17, tragically died after their climbing platform collapsed while working on the Unity Building in Liverpool on May 19, 2021. Witnesses described the horrifying moment as the platform plummeted 14 storeys, with sounds likened to a rollercoaster before it went into free-fall. David was pronounced dead at the scene due to 'massive blunt force chest injuries', while Clayton succumbed to severe brain damage in hospital four days later. Eyewitness Thomas Blanchfield recounted seeing the father and son trying to brace themselves as they fell. Reports indicated that the platform's brakes had failed, leading to the catastrophic accident. The incident has raised significant concerns about safety standards on construction sites.
