Flying Our LEGO XB-70 supersonic jet in the Snow – Real Test on a Snow Runway!

JJBrothers are back with the second test flight of our LEGO supersonic jet XB-70 Valkyrie — but this time, we’ve moved the runway to our snowy front yard!
Can this LEGO-built Mach 3 jet handle winter weather and soft snow landings? Watch us test stability, do multiple flight tests, make mid-flight repairs, and have a whole lot of snowy fun.

🌨️ Real-time snowstorm
🧱 Landing gear malfunctions
😂 Giant snowballs & LEGO drama
