A new supersonic jet set to become the new Concord could be commercially ready by 2028.
US manufacturer Spike Aerospace's futuristic aircraft aims to cut cross-Atlantic flight times in half - meaning it can you from London to New York in just three and a half hours.
The firm eventually wants to cut this time to 1.5 hours the following decade.
With a travel speed of Mach 1.6 (over 1227mph), the S-512 Supersonic Jet matches that of the classic Concorde.
However, Spike's modern version features a number of upgrades - including low sonic boom levels and a commitment to a 'Zero Carbon' flight by 2040.
Entering service in 1976, the original Concorde was extremely advanced when it was first used but became outdated at the turn of the millennium.
Using triple the amount of carbon dioxide as the modern equivalent, it was eventually discontinued in 2003.
The S-512 could be the environmentally-friendly answer to replacing the speed of the Concorde, with Spike Aerospace founder and CEO Vik Kachoria saying: "From the beginning of time, people have wanted to travel places faster.
"Getting places faster means increased opportunities. Whether that's riding a camel instead of walking or flying across the Atlantic in six hours rather than spending four weeks on a steamship.
"But imagine a six-hour flight becoming a three-hour flight. That's what supersonic offers."
The speed of the vehicle is double that of any other airplane on the market today, and will be capable of transporting up to 18 passengers on 3,000-mile trips such as London to New York or Dubai to Hong Kong in around three and a half hours.
On the topic of noise reduction, Kachoria added: "The Concorde was ridiculously noisy. Most conversations between two people are between 65 and 75 decibels and the noise level found within most plane cabins is around 85 decibels.
"Not quite a vacuum cleaner but not far off. Our windowless aircraft will be about 60 decibels, so lower than the sound of a conversation. No noise-cancelling headphones required."
Spike Aerospace is hoping to conduct trials next year with an aim to have the jet ready for commercial flights by 2028.
But they're not stopping there - the company is also planning to get the speed up to Mach 3.2 (2455mph) over the next ten years, meaning a trip from London to New York would only take an hour and a half.
If you're interested in booking one of these flights when the time comes, ticket prices may start off high, but are expected to gradually lower to around the cost of a Business Class seat on a regular flight.
Kachoria added: "Remember, almost every technological innovation we've had has started out for the uber-rich: cars, telephones, computers, flat-screen TVs - the first ones cost $25,000 in the 90s and now they're $200."
