GEM 63XL Static Fire in Snow

This was a really cool static fire of a GEM-63XL solid rocket motor. It was snowing fairly heavy and you could not see the building where the motor was firing out of. Once the motor lit, all you see was the exhaust flame through snow and fog. This motor has roughly 117,000 lbs of propellant and can generate up to 455,000 lbs of thrust. A neat element to this static fire was that it was particular more loud and rumbly than similar static fires. The reason for this was all the snowfall and cloud coverage which reflects sound waves off the clouds and ground and the sound can travel incredible distances when this happens. The closest town, Tremonton, people described the sound waves as an "earthquake" which rattled their houses and windows. From what people were saying, sounds like this static fire could be heard and felt from over 30 miles away, which is shocking considering this is not the largest motor that we static fire at Promontory.
