>>1564053>Full afterburner at takeoff
Yeah this is loud, but had SSTs continued to develop instead of essentially ending for multiple decades with the Concorde, you'd undoubtedly be seeing designs where afterburner is not required for takeoff, bringing noise levels close to the airport in line with regular jets.>then a gigantic BOOM BOOM as it hits mach speed
This doesn't happen anywhere near the takeoff period though. The video you posted clips to a point out over the ocean where it actually breaks the sound barrier. It's not like they're going supersonic once they hit 10k AGL over Long Island, and limiting them to going supersonic at 50k-60k would have pretty much eliminated the boom for anyone on the ground for overland routes.>0:58 shows how cramped the cabin is
I dunno boss, that's a lot more spacious than a modern 737, which routinely does 5-7 hour flights. Similar to a 1-2 layout or 2-2 layout regional jet. Technically smaller fuselage area, but the seat layout gives much more personal space per passenger than you'd have on a larger jet. Also, it's not like these seats were the 30" pitch you'd get on modern Delta, American, or LCCs.
