New York to London in just over three hours?
Supersonic jets are trying to make a comeback.
The start-up Boom Supersonic released a demonstrator aircraft called the XB-1.
It's a model for their future commercial airliner that Boom hopes will take you anywhere in the world in four hours.
The Overture aircraft wants to be 100% carbon-neutral and accessible.
The company is hoping to eventually charge just $100 per trip with plans to start flying in 2026.
