Once there were twin towers in Noida, taller than Qutub Minar.

Nine years after residents took to the court that the sky-high buildings were illegal, they were razed to the ground on August 28 in under 9 seconds.

The towers were brought to the ground in seconds literally like a house of cards by the 'waterfall implosion' technique, in a breathtaking spectacle of modern-day engineering.

Over 3,700 kg of explosives were used in the implosion that brought down the building.

The demolition of the structures leaves behind an estimated 35,000 cubic metres or 55,000 tonnes to 80,000 tonnes of debris which chiefly includes concrete rubble, steel and iron bars and would take another three months to be properly disposed of.

The towers were proposed to have 40 floors with 21 shops and 915 residential apartments with a fascinating view of the city. Now, the towers are nothing more than debris, dust and a once-has-been.
