BREAKING: FAA officially announced the rulemaking to legalize supersonic flight, including the Boomless Cruise ("Mach cutoff") approach we demonstrated on XB-1.
This is a major step toward the supersonic renaissance.

FAA begins rulemaking to legalize overland commercial supersonic flight using Mach-cutoff techniques
Story Overview
The FAA has started the formal process to replace its 1973 blanket prohibition on civil supersonic flight over land with a noise-based performance rule, explicitly nodding to techniques like Mach cutoff that keep the boom from reaching the ground.

Industry Shift
From blanket ban to measured noise limits
Operators would need to prove surface overpressure stays at or below 0.11 psf using FAA-approved testing or modeling, removing the need for case-by-case special flight authorizations once compliance is shown.
Open Question
Many details still to be settled
The comment period, final rule language, landing-and-takeoff noise standards, and real-world service timelines all remain open questions after this initial proposal.
Sentiment
Many users celebrated the FAA's supersonic flight legalization and noise rules as amazing progress and a big step for Boom Supersonic innovation.

We're so back! Congrats @realDonaldTrump @SecDuffy on making America boom (quietly)!

PRESIDENT TRUMP IS CLEARING THE RUNWAY FOR SUPERSONIC FLIGHT ✈️
Today, as directed by @POTUS's EO, @USDOT proposed new rules for noise limits instead of speed limits for next generation supersonic aircraft.
American ingenuity broke the sound barrier once before. Supersonic innovation means quieter, faster, and safer travel for people and goods across the country.

@bscholl @grok what did the FAA say?

While this is a step forward, I am concerned that this rule in practice only legalizes Mach cutoff flight.
This effectively means we are increasing the speed limit from Mach 1 to Mach 1.15 or so. Furthermore, Mach cutoff is an incredibly inefficient mode of operation, so very few flights will use it.
The 0.11 psf limit is way too strict. I hope that in the final rule FAA adopts a true low boom standard.
