Have you done an 8 hour flight in economy? It's absolutely miserable. Noise pollution over the Atlantic affects literally noone.

Yes and if you're talking about economy you will never be able to set foot on a plane like this either. There are proposals to have this over land as well which I am very strongly against to the point of not wanting a company like this to be successful.

Air NIMBY!

On a serious note, the only way this gets overland approval is if it’s comparably loud to existing options. Which given the work that’s been done on sonic booms, and some of the old kit that still flies, isn’t as hard as you’d think.

Are you unfamiliar with the work NASA is doing on sonic boom reductions? Or are you too cynical to care?

Very familiar, but even regular planes are loud as hell already since I happen to live between the airport and a holdover route.

Idk what altitude planes are at in a location like yours, but there is certainly going to be an altitude limit on supersonic flight over land.

I don't care if I can't, some people can. Good for them.

You can pay for business or first class. Supersonic flights won’t be cheaper.

Didn't say they would be.

It likely has an affect on whales and other marine animals as shown by a number of studies previously.

I've completely forgot about this! It also affects other airplane systems (mostly pito tubes) which can cause the autopilot to disconnect or master caution to go off which have been known to lead to confusion and major incidents in the past.

It's not like they are flying at 1000 feet above the ocean. at between 30-40k feet, if you can hear the jet engines, you are a lucky whale!

You can in fact hear super sonic flight above you even at 30 to 40k feet, think of the noise that spacex falcon rockets produce, but it's hard to compare legitimate explosions going off every millisecond to a needle piercing the sky.
