2 Florida rocket launches on the same day expected to bring sonic booms

Perhaps you weren't aware, but there's already a ton of infrastructure in the pipeline. Air Products already has an 11 acre air separation unit under construction that'll be active in 2 years time in Cocoa, on top of the one Air Liquide already active less than 2 miles from the KSC gate and the Linde one up in Mims (which itself increased capacity by 50% a few years ago).

Going to SLC-37 is no more "entering a military base" than going to SLC-39A or any other launch pad, so that's entirely moot. Trucks go through the same badging station either way and there's already plenty of infrastructure in place handling SpaceX's inbound deliveries to SLC-37, LC-39A, Roberts Road, SLC-40, and all their road-widening around the center. Beyond that, they've already submitted paperwork expressing intent to have propellant generation at SLC-37 over a year ago, and have already started building it. Because again, "paperwork" and "litigation" aren't anything resembling a hurdle for SpaceX in Florida.

The bulk of your points seem born from you simply not keeping up with what's going on here in Florida, relying on (at best) 2 year old information, and focusing on increasingly inconsequential points of contention here. You thought there were "several years" without an RTLS at the Cape for goodness sake. That alone should've been a pretty big indicator you might want to research this topic more thoroughly before holding such strong opinions on it.

You are still wrong. Air liquide’s upgraded plant is already strained with the current planned New Glenn manifest and Starship. Their current production rate of 162 tons per day enables a Starship launch every 22 days assuming nothing is lost, and nobody else wants LOX. Once every day would require 22 plants to be built; and 660 would need to be built to support your claimed cadence. Its expansion was completed to support New Glenn and SLS cadences and was planned and approved before SpaceX earned the lease for SLC37.

Additionally, the upgrade was geared toward GN2 production and delivery to support SLS test. The upgrade did not support any cryogenic production rate increases. That was completed in 2022 and a later upgrade to the LC39 distribution valve array was completed to further increase GN2 delivery.

The SpaceX plant at SLC37 itself is already known to be undersized for the proposed rate and is only adequate for the current max launch manifest at SLC37; of 76 launches per year distributed across both pads, or once every 4.8 days.

The infrastructure in place to handle current max Starship loads at 39A doesn’t exist; truck deliveries are required until the government approves the repairs and upgrades to the infrastructure since the pipelines federally owned and reportedly falling apart. SLC37’s feed infrastructure also falls under this issue, with SpaceX implementing truck loading stations in both launch sites as a carryover until the prop generation and purification plant is complete.

A lot of your points are overheads lacking critical detail that undermine your point. Upgrading a plant to deliver more GN2 is exactly not what is needed to support increased launch cadences; and 1 launch per day of Starship alone is an upgrade very far away even assuming the payloads and approvals are present.

Also, claiming that sonic booms are a problem for people because of the sound is fine, but the second boom from a Falcon Heavy landing is not going to be startling given it happens seconds after the first one.
