Here’s an interesting article regarding two 17 year olds Canadians who managed to send a LEGO Minifigure 24 Kilometres (~15 miles) above sea level. Pretty cool! Thanks to Peter and forum member harry99 for the news.
Two weeks ago, Ho and Muhammad launched a homemade balloon carrying a Lego passenger and four cameras. It fell back down to Earth 97 minutes later with astonishing footage from an estimated 24 kilometres above sea level, three times the typical cruising altitude of a commercial aircraft.
