The Andaman and Nicobar Islands have successfully set a new Guinness World Record for the tallest underwater human stack, reaching a remarkable height of 22.3 metres with 14 scuba divers on May 3, 2023. This achievement took place at the Lighthouse dive site in Swaraj Dweep, just a day after the region unfurled the largest national flag underwater, measuring 60 × 40 metres at Radhanagar Beach. The event aimed to highlight the islands as a premier destination for diving and underwater activities. Lieutenant Governor Admiral D.K. Joshi led the divers and participated in the formation, which required precise coordination and balance. Following the successful record attempt, a ceremony was held at the Dolphin Resort, where Guinness World Records adjudicator Rishi Nath officially confirmed the record and presented a certificate to the Andaman and Nicobar Administration. Admiral Joshi commended the teamwork that made this achievement possible, emphasizing its role in attracting global attention to the islands. Various local authorities, including the Tourism Department and Indian Navy, supported the event, showcasing the collaborative spirit of the community.
