Motor wound up.

About 8 seconds in the prop leaves and a second later you can hear the motor rev up to god only knows how many RPMS. To address this specific point, note that the video is being shot with a telephoto lens from a mile or three away. Because sound is so much slower than light (about 750 mph versus 186 000 miles per second), what you hear of a distant event lags substantially behind what you see of it. So even though you see the prop depart and then hear the motor wind up, it probably did not happen in that sequence. Thanks again, Bob K. |
