Transatlantic flights are not inherently dangerous. Commercial airlines adhere to strict safety regulations and protocols to ensure the safety of their passengers. The aircraft used for transatlantic flights are designed to withstand long-haul journeys and are equipped with advanced safety features. Additionally, pilots undergo rigorous training and are experienced in handling long-distance flights. While there are always inherent risks with air travel, transatlantic flights are generally considered safe. **

The cheapest plane for a transatlantic flight would typically be a budget airline such as Norwegian Air Shuttle or WOW air. These airlines offer lower prices compared to traditional carriers like British Airways or Delta. However, it's important to note that budget airlines may charge extra for amenities like meals, baggage, and seat selection, so travelers should factor in these additional costs when comparing prices. **

Yes, you typically need a sailing license for a transatlantic voyage. The specific requirements for a sailing license can vary depending on the country you are departing from and the country you are arriving in. In addition to a sailing license, you may also need to meet certain experience and training requirements, as well as have the necessary safety equipment and emergency procedures in place for a transatlantic voyage. It is important to research and comply with the regulations of the countries involved in the voyage. **

To cope with knee pain during a transatlantic flight, it is important to regularly stretch and move around to prevent stiffness and improve circulation. Consider doing simple knee exercises while seated, such as ankle circles and knee lifts. Additionally, using a small pillow or blanket to elevate your feet slightly can help reduce pressure on your knees. It is also advisable to wear comfortable, loose-fitting clothing and stay hydrated throughout the flight to help alleviate knee pain. **

In case of an emergency during a transatlantic flight, the plane can land at the nearest suitable airport. This could be an airport along the flight path or a diversion to a closer airport if necessary. Airlines and pilots are trained to handle emergency situations and will make the decision on where to land based on the nature of the emergency, the available airports, and the safety of the passengers and crew. **

Ground effect vehicles, also known as wing-in-ground effect (WIG) vehicles, are designed to operate close to the surface of the water, taking advantage of the ground effect to achieve greater lift and efficiency. While they can be used for short-haul passenger operations over water, they may not be suitable for transatlantic passenger operations due to several reasons. First, ground effect vehicles have limited range and speed compared to traditional aircraft, making them less practical for long-haul flights. Additionally, they may be more susceptible to weather and sea conditions, which could pose safety and operational challenges during a transatlantic journey. Finally, the infrastructure and regulatory framework for ground effect vehicles may not be well-established for transatlantic operations, further limiting their feasibility for such long-distance travel. **

As an AI, I do not have the ability to physically travel. The Transatlantic Tunnel is a fictional concept that connects Europe to North America, not specifically England. It is a popular idea in science fiction and speculative fiction literature, but it does not exist in reality. **
