Upon landing in New York, just 54 minutes after departure.
Although that may seem like something from a science fiction novel, this is exactly what a proposed Transatlantic Tunnel claims it will accomplish.
This Elon Musk-backed concept could enable travelers to finish the 5,470-kilometer (3,400-mile) trip in less time than many people spend commuting within their own city.
However, that convenience comes with a significant cost, with the estimated price tag reaching $19 trillion (£15 trillion), more than five times the UK's total GDP.
There has been a renewed interest in the idea that his tunnel-digging company, The Boring Company, could complete it for '1,000 times less money'.
Although it may seem far-fetched, the fundamental technology required to construct the tunnel has already been established.
Using vacuum tubes and magnetically levitating trains, friction could be almost completely eliminated.
This could enable speeds of over 3,000mph (4,800kmph) while traveling in a remarkably smooth manner, so much so that it would be possible to drink a cup of coffee without spilling it.
Although the concept is futuristic, the first proposal for a tunnel connecting Britain and America first appeared in a 1895 story by Michel Verne, the son of science fiction author Jules Verne, entitled 'An Express of the Future'.
In 1913, German author Bernhard Kellerman wrote a novel called "The Tunnel", which served as the basis for the 1935 English-language film version titled "Transatlantic Tunnel".
In recent times, engineer Robert H Goddard, who is credited with inventing the first liquid-fuelled rocket, received two patents for his tunnel designs in the early 1900s.
However, it is only in recent times that a combination of two technologies has brought the Transatlantic Tunnel closer to becoming a reality.
The first is the development of magnetic levitation (maglev) trains, which utilize powerful electromagnets to elevate the train above the tracks.
By eliminating the points of contact between the train and the track, the friction that slows the vehicle down is significantly diminished and the maximum possible speed is greatly increased.
This technology is not only a reality, but it is also commonly utilized in countries like Japan, Germany, and China.
.
This is approaching the speed of a Boeing 737 plane at cruising altitude, which is approximately 560 miles per hour (or 901 kilometers per hour).
China already has two maglev train lines - Changsha Maglev and Shanghai Maglev - but these only operate at speeds of up to 62 mph (101 kmph) and 268 mph (431 kmph), respectively.
To achieve speeds comparable to commercial airliners, maglev trains must be paired with vacuum tubes.
This second innovation suggests that train tracks could be constructed within specially designed, covered enclosures.
By removing the air from these tunnels, this 'hyperloop' design could almost completely eliminate the friction caused by air resistance.
In theory, this could enable hyperloop trains to reach speeds exceeding 965 kilometers per hour.
Elon Musk has been a significant advocate for this technology and has claimed that a hyperloop tunnel could be constructed between San Francisco and Los Angeles.
Although the technology is still in its early stages, there have already been several encouraging advancements.
.
In 2024, the European Hyperloop Centre successfully operated a full-scale test vehicle at speeds comparable to the average metro train.
Reaching a top velocity of 387 miles per hour (622 kilometers per hour).
In theory, this technology could be used to transport travelers through vacuum tubes all the way from London to New York.
Although the trains could potentially reach the desired speeds, the main challenge lies in constructing the tunnel itself.
The distance from New York to London, at 3,400 miles (5,470 km), far surpasses the length of the Channel Tunnel, which links the UK and France.
Even that 23.5-mile tunnel cost £4.65 billion, which is equivalent to approximately £12 billion today, and took over six years to finish.
A proposed undersea tunnel connecting Spain and Morocco has been delayed due to 'unforeseen geological challenges'.
The proposed connection was intended to span approximately 17 miles at a maximum depth of 1,550 feet.
However, Spain's Transport Minister Oscar Puente stated: 'The conditions are far more complicated than initially anticipated.'
The project's original completion target was 2030, but it now appears unlikely that this deadline will be met.
The proposed Transatlantic Tunnel could encounter even more challenging geological circumstances that might hinder its construction.
Regardless of its construction, the tunnel will have to navigate the Mid-Atlantic Ridge, a vast underwater zone of volcanoes created by the movement of the South American and African tectonic plates.
The movement between these plates forms a mountain range 1.8 miles (3km) high and 930 miles (1500 km) wide, where lava flows continuously from cracks in the Earth's surface.
Constructing an air-tight, vacuum-sealed tunnel to traverse that rift would pose a highly intricate engineering challenge.
