Marvel heroes to light up Han River in Seoul’s final drone show of year

What happened: Seoul will hold its final Han River drone light show of the year on Saturday at Ttukseom Hangang Park, with 2,000 drones forming Marvel characters and movie scenes. Key numbers: 2,000 drones; 15-minute show starting 8:30 p.m. Why it matters: It uses the largest number of drones deployed for the city's Han River show, and average attendance has risen sharply since the series began. With the finale on Halloween, the city plans extra safety personnel and subway services, and trains may bypass Jayang Station if crowding poses safety concerns.
