Airplanes are important, because they allow people and goods to be transported quickly over great distances and over all types of terrain. Before the advent of safe and convenient travel by airplane, journeys took much longer and were more difficult.
According to HowStuffWorks, airplanes are capable of transporting people and parcels to the other side of the world in less than a day. Long voyages by ship are no longer a necessity to cross the world's oceans. Letters and packages arrive to distant destinations quickly and safely through air transport. Airplanes deliver supplies quickly to remote locations in emergency situations and restock military operations. Airplanes also improve medical care by quickly moving patients from rural areas to large medical centers and transporting organs to distant locations for transplants.
