A new plane design could mean that flights between London and New York take just 80 minutes in coming decades.
The 328ft-long Hyper Sting supersonic plane could hold up between 130-170 passengers and in theory it could reach a maximum speed of 2,664 mph.
For context, Concorde reached speeds of up to 1,354 mph.
Spanish designer Oscar Viñals is behind the design, which he says could travel at up to three times the speed of sound, reports the Daily Star.
He explains that a Mach 3.5 capability would be thanks to innovative systems like a so-far theoretical 'cold fusion nuclear reactor'.
This would power two ramjet engines and four next gen hybrid turbojets.
Oscar explains: "Concorde was a brilliant piece of machinery, a noble experiment, but it put too much emissions in the environment, too much noise into our communities, and was too expensive to operate.
"A new era of supersonic flight might be just around the corner, but there are challenges to overcome when it comes to flying faster than the speed of sound.
"The Hyper Sting is a new concept for future supersonic commercial airplanes.
"Today, there are some projects for a new era of supersonic flights from different private and public initiatives, some of those are well underway and could become in few years in a real concept."
As for the name, this is inspired by the aircraft's shape, with a 'very sharp nose'. The sleek design aims to "have the function to control the front airflow (pressure/speed), in order to redistribute it over the central part and over the wings".
Unfortunately before you start planning a quick weekend in the Big Apple, technology needs to catch up.

Although the Barcelona-based designer believes his concept is feasible, he caveats that for it to come to fruition, there needs to be advances in technology.
He predicted: "Supersonic flights will return, but in this case due to some very innovative systems, like the cold fusion reactor, the date of a possible production, would be over 2030 and the cost would not be cheap."
It's not the only aircraft of this nature to be aiming to launch in coming years.
The 'world's fastest airliner' is currently planned for a launch in 2029 which could fly between London and New York in just 3.5 hours.
Boom Supersonic previously gave a sneak peek at the latest design for their Overture plane, which is set to be rolled out in 2025, with the aim to have passengers onboard by 2029.
The plane will be able to carry 65-80 passengers, and will fly Mach 1.7 (the measurement used for the speed of sound), with aims to run on 100% sustainable aviation fuel.
The company has said that it is aiming to begin production in 2024.
