When a plane goes supersonic, it exceeds the speed of sound, which is approximately 343 meters per second (1,125 feet per second) in air at sea level. This results in the formation of shock waves, creating a sonic boom that can be heard on the ground. The aircraft experiences changes in aerodynamic forces, leading to increased drag and potential instability, requiring advanced engineering to manage these effects. Supersonic flight is typically limited to military aircraft and specialized civilian planes due to regulatory and environmental concerns.

You weigh slightly less in a high-flying airplane due to the effects of gravity and altitude. As you ascend, the force of gravity decreases because gravitational pull weakens with distance from the Earth's center. Additionally, the acceleration of the airplane can counteract some of the gravitational force, leading to a temporary reduction in weight. However, this difference is minimal and generally imperceptible to passengers.

The landing speed of the McDonnell Douglas MD-90 typically ranges between 130 to 150 knots, depending on factors such as aircraft weight, configuration, and environmental conditions.

An airplane attempting to fly higher than 30,000 feet will encounter several challenges, including reduced air density, which can affect engine performance and lift. Additionally, regulatory restrictions and oxygen requirements for pilots and passengers may come into play, as the air at those altitudes becomes too thin for unpressurized cabins. Most commercial aircraft are designed to operate efficiently within a specific altitude range, typically between 30,000 and 40,000 feet. Flying higher than this can also increase the risk of encountering severe weather phenomena, such as turbulence and icing.

The sound of a plane flying overhead typically consists of a deep, rumbling roar that can vary in intensity depending on the type of aircraft and its altitude. As the plane approaches, the noise often increases in volume, characterized by a combination of engine noise and the whoosh of air. When it passes overhead, the sound can create a distinct Doppler effect, where the pitch changes as it moves away. This can evoke feelings of awe or disturbance, depending on the context and frequency of air traffic.

The Federal Aviation Administration (FAA) is a United States government agency under the Department of Transportation responsible for regulating civil aviation. Its primary roles include ensuring the safety of air travel, managing air traffic control, and overseeing the certification of pilots and aircraft. The FAA also develops regulations and policies to promote the efficiency of the national airspace system and supports advancements in aviation technology.

A typical jumbo airplane, such as the Boeing 747, can accommodate between 400 and 600 passengers, depending on its specific configuration and layout. For example, a standard two-class layout might seat around 416 passengers, while a high-density, all-economy configuration could hold over 600. Additionally, variations in airline configurations and seating arrangements can further influence capacity.

Propellers generate thrust by converting rotational energy into forward motion, which helps lift the airplane. As the propeller spins, it creates a pressure difference between the upper and lower surfaces of the wings, contributing to lift. If the thrust generated by the propellers is sufficient to overcome gravity, the airplane can climb to a higher altitude. Conversely, if thrust decreases or drag increases significantly, the airplane may struggle to maintain or gain altitude.

In twin screw ships, the propellers are typically designed to rotate in opposite directions, which helps to counteract the torque produced by each propeller, enhancing stability and maneuverability. This configuration allows for better control during navigation, especially during turns, as the opposing thrust generates lateral forces that aid in steering. Additionally, the arrangement improves efficiency and reduces the likelihood of cavitation, contributing to overall performance.
