The City of Port Angeles is clearing some land for a new business, but there's an old steel reinforced concrete smokestack. So they try to blow it up. At first, almost nothing happened. Then, nothing continued to happen.
Not enough dynamite or whatever. They did eventually get it down hours later but I wasn't present.
There are several interesting things to notice in this video:
1: Note the delay between the smoke burst at the tower, and the time the sound reaches the camera.
2: Note the time delay between when the sound reached the camera, and I jumped upon hearing the sound.
3: Note the small RC quadracopter flying around observingReport Video
