Final answer:
Drones are often impossible to use for international shipping, while trucks, trains, airplanes, and ships are viable options.
Step-by-step explanation:
In logistics and transportation modes, shipping can be a very costly endeavor for companies, especially when shipping from one country to another. When it comes to shipping goods internationally, one mode of transportation that is often impossible to use is drones. Drones are typically used for local or short-distance deliveries, and they are not practical for long-distance shipping due to their limited payload capacity and range.
On the other hand, trucks or trains, airplanes, and ships are commonly used for international shipping. Trucks or trains are suitable for domestic or cross-border transportation, while airplanes are ideal for faster delivery of time-sensitive goods. Ships, particularly cargo ships, are widely used for shipping goods over long distances.
In conclusion, when it comes to international shipping, drones are often impossible to use, while trucks or trains, airplanes, and ships are viable options depending on the specific requirements of the shipment.
