The XB-1 was built to learn all the necessary lessons for creating a supersonic jet that is safe for passengers, using technology that can be deployed on commercial airliners.

Boom, a company funded by Y Combinator, is developing a supersonic passenger jet and made significant progress during their batch by securing a $100 million LOI from Richard Branson.

Overture, the upcoming supersonic airliner, will carry around 65 passengers, travel at Mach 1.7, and run on 100% sustainable fuel, while also preventing sonic booms from reaching the ground, allowing it to fly over land.

Eight years after their Y Combinator batch, Boom successfully built and flew a supersonic jet, demonstrating the potential of hard tech startups.

Building a supersonic jet is incredibly challenging, but it's not impossible. It requires a unique approach and a willingness to learn from mistakes along the way.

Supersonic travel will enter the market similarly to other technologies, starting at higher price points and gradually becoming more affordable, much like electric cars and smartphones.

I set a lifetime goal in my 20s to fly supersonic after seeing a Concorde in a museum, and I believe the future should include flights that are at least twice as fast as current speeds.

Astrome Mechanica has developed an electric jet engine that is efficient at all speeds, allowing for versatile applications in aviation.

I initially thought there was no way I could be the one to discover the formula for supersonic passenger flight, but it turned out to be liberating to realize that I could find the flaws in the existing assumptions.
