New York to London in 3.5 hours. But at what cost? ✈️💸 We investigate Boom Supersonic and their flagship jet, Overture. We break down the promise to revive the "Golden Age" of the Concorde without the failures. We analyze the XB-1 test flights and the custom "Symphony" engine designed to silence the sonic boom, asking if speed is finally sustainable.

1. The Concorde Curse: Why did it die? We analyze the history. We discuss the three killers of the Concorde: Noise (it was banned over land), Fuel (it was inefficient), and Cost (tickets were $12,000). We explain that for Boom to succeed, they have to solve the physics of the "Sonic Boom" that shattered windows and laws in the 1970s.

2. The 7x Fuel Problem: Faster means thirstier. We expose the data. We discuss the uncomfortable truth that flying supersonic requires brute force. We analyze reports showing the Overture burns 7 to 9 times more fuel per seat-mile than a standard subsonic jet. We ask: in a world fighting climate change, can we justify burning that much kerosene to save 3 hours?.

3. The SAF Gamble: Flying on cooking oil? We explore the solution. We discuss Boom's pledge to run on 100% Sustainable Aviation Fuel (SAF). We break down the supply chain crisis: SAF currently makes up less than 0.1% of global jet fuel. We explain that Boom's entire business model relies on a fuel that effectively doesn't exist yet at scale.
