This submission was flagged on HN but it was pointed out.

> In addition to the siting and sizing of the pad, SpaceX does not have a flame trench, nor do they have a water deluge system used to suppress heat and sound energy from any launches, as the Army Corps of Engineering permitting required to add these civil engineering systems is itself a multi-year process.

> No large rocket complex on the planet: not in Russia, nor China, and certainly not in the US, exists that doesn’t contain one or both of these energy suppression systems.
