No, airplanes, private jets, and similar modes of transportation do not belong to public transportation. Public transportation typically refers to services that are available for use by the general public, such as buses, trains, and subways. Airplanes and private jets are usually privately owned or operated for specific individuals or groups, rather than being accessible to the general public. **

Paper airplanes and real airplanes look different because they serve different purposes and are made of different materials. Paper airplanes are simple, lightweight toys made from folded paper, designed for short-distance flights. Real airplanes are complex machines made of metal and other materials, engineered for long-distance travel and carrying passengers or cargo. The shape, size, and materials used in real airplanes are carefully designed to ensure stability, lift, and control during flight, which is not necessary for paper airplanes. **

Yes, small airplanes can see other airplanes on certain apps designed for aviation. These apps use ADS-B (Automatic Dependent Surveillance-Broadcast) technology to display the location and identification of nearby aircraft. Pilots can use these apps to enhance situational awareness and avoid potential conflicts with other aircraft. However, it's important to note that not all small airplanes may be equipped with the necessary technology to be visible on these apps. **

Passenger airplanes are designed specifically for carrying passengers from one destination to another, while transport airplanes are designed to carry a variety of cargo, including goods, equipment, and sometimes passengers as well. Passenger airplanes are equipped with amenities and features to ensure the comfort and safety of the passengers, while transport airplanes are designed to efficiently transport cargo with minimal amenities. Additionally, passenger airplanes typically have a larger focus on passenger comfort and entertainment, while transport airplanes prioritize maximizing cargo space and weight capacity. **

It is highly unlikely that airplanes will become a regular part of local public transportation. Airplanes are better suited for long-distance travel and are not practical for short distances within a local area. Additionally, the infrastructure and logistics required for incorporating airplanes into local public transportation would be extremely complex and costly. Other modes of transportation, such as buses, trains, and subways, are much more practical and efficient for local travel. **

Airplanes can squeak due to a variety of reasons, such as friction between moving parts, changes in air pressure during flight, or vibrations caused by turbulence. These noises are typically harmless and are a normal part of the aircraft's operation. However, if the squeaking becomes excessive or is accompanied by other unusual sounds, it may indicate a maintenance issue that needs to be addressed. Regular maintenance checks and inspections help ensure that any potential problems are identified and resolved promptly. **

Yes, there are electric airplanes currently in development and some already in operation. These electric airplanes use electric motors powered by batteries instead of traditional combustion engines. They offer the potential for reduced emissions and noise compared to traditional aircraft, making them a more environmentally friendly option for air travel. However, electric airplanes are still in the early stages of development and face challenges such as limited range and battery technology constraints. **

No, Edeka is a German supermarket chain and does not have airplanes. Edeka primarily operates grocery stores and does not have any known involvement in the aviation industry. **
