On September 8, 1991, a countdown commenced on a pair of notorious Niddrie tower blocks that were to be sent crashing to the ground - or at least that was the plan.
But despite the button having been pushed, both Teviotbank House and Tweedsmuir House, which had only been completed 19 years earlier, were still standing.
Embarrassingly, the detonation had failed, and it would take demolition experts nine hours to topple the tower blocks bit-by-bit with a mechanical digger.
