Are you freaking deaf?!
I work with sound every day, please do tell me what you hear in this video so I can embarrass you about how sound works.
And what about the dust cloud? Gage claims that can only happen with a demolition but as Chris showed you in his videos that is what will happen when a building collapses either from explosive demolition, Verinage demolition or fire. Explosives arent even creating the dust cloud, thats still the building crushing into itself. What do you think the dust cloud tells you?
Once ps: if it fell accross a 4 lane street critically damaging the building there, it can't be very symmetrical and clean straight into its own footprint can it?
