An unexploded World War II bomb was discovered in the River Thames by the runway of London's City Airport.
It shut for the day while Royal Navy divers removed the bomb, affecting 16,000 customers.
The bomb was dragged 60km to sea on Tuesday, and destroyed on Wednesday.
An unexploded World War II bomb that forced a London airport to close has been detonated at sea by the Royal Navy.
The 500-kilogram, 1.5-metre-long tapered-end shell was blown up with high-grade military detonators off the coast of Essex, where the bomb was transported earlier this week.
The Royal Navy tweeted photos of divers setting out to sea to detonate the device on Wednesday morning.
A navy spokeswoman confirmed to Business Insider that the explosion took place just after midday.—Captain MFP (@CaptainMFP) February 14, 2018 ' data-e2e-name="embed-container" data-media-container="embed"> —Royal Navy (@RoyalNavy) February 14, 2018 ' data-e2e-name="embed-container" data-media-container="embed">
