Colby Bull has swum to and from Alcatraz and crossed Lapland by sleigh over seven days. For his latest stunt, the London collector and founder of the rare-collectibles business Edition One climbed onto the wing of a 1940s biplane roughly 600 feet above Kent, England, and opened seven packs of basketball cards before the minute was up.
Guinness World Records certified the feat — the most trading-card packs opened during a wing walk in one minute — the day after the October 13 flight, operated by The Wing Walk Company out of Headcorn Aerodrome. Bull opened seven packs of 2025-26 Topps Chrome Update Series basketball cards while harnessed to the wing of the Boeing Stearman, in winds he estimated at roughly 120 mph. He lost none of the cards to the wind.
"Seven packs felt like seventy"
Bull described the attempt as considerably harder than it sounds. "I wanted to see what it felt like full of adrenaline," he told the collectibles outlet What's The Jam after the flight. Describing the time pressure of working a card pack open with gloved hands in a 120 mph headwind, he said: "Seven packs felt like seventy." He added, with some self-awareness about his growing list of unusual feats: "People must think I'm a lunatic."
The record sits at an unusual intersection of two niche worlds — extreme wing-walking stunts, typically associated with charity fundraisers and aviation enthusiasts, and the trading-card market, which has seen a resurgence in collector interest and resale prices in recent years. Guinness has certified a number of trading-card-related records in the past two years as collecting has boomed, but officials say this is the first to combine card-opening with an aerial stunt.
What's next
Bull has not announced a follow-up attempt, though his pattern of record chasing — each one more elaborate than the last — suggests another is likely. For now, the record stands as a curiosity at the edge of two fast-growing hobbies: extreme personal challenges performed for an online audience, and a collectibles market where opening a pack on solid ground is enough to draw millions of views on its own.
