Before the sun came up on a cold December morning, the crew turned on the four large blowers that were to inflate the structure. They said it should take about three hours to completely inflate, which gave my team plenty of time to set up the four time-lapse cameras, a drone, and several ground video cameras. Next thing we knew, the roof was up within minutes, including that big heavy ring. We were not ready! Think about this, an entire weather-sealed, full-size gymnasium was completely standing in about 45 minutes!
