Media 10, the organizers of Destination Star Trek London wanted to break the Guinness World Record for “The Largest Gathering of People Dressed as Star Trek Characters,” and it’s now been officially confirmed by Guinness World Records. It took place on October 20, 2012 at the ExCel London. That’s when and where 1,063 gathered together in costume, besting the previous record 1,040, set at a Trek convention in Las Vegas two years ago.
I will say I was one of those 1,063 people all gathered in the talks hall of which the 5 captains gave their talks together over the 3 days. It was a lot of fun and also great to be part of a world record achievement.
