Revolutionary Radar System Enhances Runway Safety at Heathrow Airport

The video discusses the importance of keeping airport tarmacs clear of debris for flight safety. A new radar system is being tested to detect debris from up to 2 kilometers away, offering speed, range, and accuracy. This system could prevent incidents like the Concorde crash, which was caused by runway debris. Despite the new technology, manual checks will continue. The system is also being tested in Canada and is set to launch next year.
