@Truthful_ast The doubled TSS pictured would only have an internal volume of ~680m^3, about 2/3rds of the ISS's internal volume.

This is a known phenomena, speed of sound is higher in warmer air, and moist air. The result is that sound waves from high altitude can get refracted upwards.
But the angle of the shock cone around a supersonic object gets steeper as the aircraft goes faster, so above a certain speed it's too steep to get refracted sufficiently.

Boom! We cracked it! Today we are introducing Boomless Cruise—supersonic flights up to 50% faster with no audible sonic boom. We quietly (har har) demo'd this on XB-1's first supersonic flight—three times actually. 🧵👇

"EGS had several months of schedule margin in its work toward a Sept 2025 launch date at the beginning of the year. But now, the program has allocated all of that margin..."
Literally how? 3 years isn't enough times to ready the ground systems between launches????????

Why am I teary over a train?? My 7yo asked what’s going to happen to the diesel @Caltrain now and I told him they were going to take the diesel trains to live on a farm where they could spend the rest of their days frolicking and driving kids around. 🥺
