In this day and age, we believe that every vehicle should come with a functioning braking system in order to ensure safety. However, from the creation of the first plane to the advancements made during WWI, the early plane had no need for a complex braking system. It flew at such slow speeds that it only relied on the friction of the wheels touching the ground in order to come to a gradual stop. But as war created the need for faster and larger planes, a functioning brake system became necessary. Contemporary aircraft now typically have a dedicated brake unit for each of its main wheels in order for it to come to a stop in a timely manner.
