Lots of people have heard of the Horton Grand Hotel in downtown San Diego, CA. Here's a view of the hotel that not too many people see - a view from the roof of this historic building. 

ISE was involved in a forensic case that required us to do some work on top of the hotel. The view is a panoramic one close to sunset looking towards the west towards Seaport Village and the convention center.

Featured Video Clip (Shock Wave)

A video taken by ISE showing the supersonic expansion of high pressure natural gas in a pipeline. 

The shock wave is clearly visible at the 1:00 min mark as a white cloud above the end of the pipe and produces an acoustic overpressure of close to 140 dB - which is as loud as a rocket engine.
