The UH-34 wasn’t the only helicopter flying at Brewster. As I was driving towards the exit, I heard the sound of a turbine whining. I pulled over to the side of the road and saw that the Life Flight helicopter was running up. I headed to a piece of higher ground that overlooked their space. The Agusta 119 Koala was sitting on a trailer and warming up. It then pulled up in to a hover and transitioned to the grass. A moment later, back to the hover and back to the trailer. This was repeated a couple of times. It didn’t seem like they were actually going flying unfortunately. As they ran down the RPMs, I figured it was time to move on again.
