Imagine arriving at a busy airport and, instead of spending an hour sitting in traffic, stepping into a small electric aircraft that takes off vertically and flies directly toward your destination.
This may sound like something from a science-fiction movie, but companies around the world are working to make this kind of transportation a reality.
One of the companies developing this technology is Joby Aviation, which is working on electric vertical take-off and landing aircraft, commonly called eVTOLs.
The name may sound complicated, but the basic idea is simple. These aircraft are designed to take off and land vertically, similar to a helicopter, while using electric propulsion.
Joby Aviation has been working with Virgin Atlantic to explore the possibility of bringing electric air-taxi services to the UK.
The partnership could eventually help passengers travel between airports and nearby cities more quickly, while also providing a new form of transportation for short journeys.
The idea behind air taxis is to solve one of the biggest problems in modern cities: traffic.
Roads in major cities can become extremely crowded, especially around airports. Travellers may spend a significant amount of time travelling from an airport to a city centre even when the distance is relatively short.
An electric air taxi could potentially fly above the traffic and take passengers directly to another landing location.
This could make certain journeys faster and provide another transportation option.
But building an electric air-taxi network is much more complicated than simply designing an aircraft.
Companies need to consider where the aircraft will take off and land, how passengers will access the service, how the vehicles will be charged and how flights will be safely managed.
These aircraft will also need to meet strict aviation safety requirements.
Aviation is one of the world's most highly regulated industries. Before passengers can regularly fly in a new type of aircraft, regulators must ensure that the aircraft and its operating systems meet demanding safety standards.
This means that electric air taxis still have a significant journey ahead before they become a common sight above cities.
One of the biggest advantages of eVTOL aircraft is their use of electric propulsion.
Traditional aircraft use jet fuel, while helicopters generally rely on aviation fuel as well. Electric aircraft use batteries and electric motors instead.
This could reduce local emissions during flight and potentially make short-distance air travel quieter.
Noise is particularly important when discussing urban aviation.
A helicopter flying over a city can be very loud. For air taxis to operate regularly in populated areas, they will need to be designed with noise levels in mind.
Electric propulsion could help, although the aircraft's rotors still produce sound.
Another interesting feature is that eVTOL aircraft are designed to combine some of the advantages of helicopters and airplanes.
Like helicopters, they can take off and land vertically. Like airplanes, many designs are intended to fly efficiently once they are in the air.
This combination could allow them to operate in places where traditional airports are not available.
However, the technology is still developing.
Battery technology is one of the major challenges. Aircraft need to carry enough energy to complete their journeys while keeping the vehicle light enough to fly efficiently.
The weight of batteries is therefore an important engineering consideration.
Companies are also exploring how air-taxi services could fit into existing transportation networks.
For example, an electric air taxi might transport a passenger from an airport to a landing site near a city centre. The passenger could then continue the journey using a train, bus or car.
This means that future transportation may become increasingly interconnected.
Instead of thinking about aviation and ground transportation as separate systems, cities could combine them into one larger network.
The partnership between Joby Aviation and Virgin Atlantic is part of a wider global effort to develop advanced air mobility.
Several companies are developing eVTOL aircraft, while regulators are working on the rules needed to safely operate them.
The UK is also interested in developing the infrastructure and regulations required for advanced air mobility.
However, it is important to remember that electric air taxis are not yet a replacement for conventional commercial aviation.
A large passenger aircraft can carry hundreds of people across continents. An air taxi is designed for much shorter journeys with fewer passengers.
Instead, eVTOL aircraft could become another layer of the transportation system.
They might be used for airport transfers, short city journeys or connections between locations that are difficult to reach quickly by road.
The next few years could be important for the development of this technology.
If aircraft certification, infrastructure and battery technology continue to progress, electric air taxis could eventually become a familiar part of urban transportation.
The skies above cities may look very different in the future.
Instead of seeing only commercial airplanes and helicopters, passengers could watch small electric aircraft quietly moving between landing sites.
For now, the technology is still taking its first major steps.
But the idea of calling an air taxi to avoid a traffic jam may not remain science fiction forever.
WHAT WE LEARNED
eVTOL stands for electric vertical take-off and landing.
Joby Aviation is developing electric aircraft designed for short-distance transportation.
Virgin Atlantic and Joby Aviation have explored the potential for electric air-taxi services in the UK.
