In addition to pilots, air forces have ground support staff who support the aircrew. In a similar manner to civilian airlines, there are supporting ground crew as pilots cannot fly without the assistance of other personnel such as engineers, loadmasters, fuel technicians and mechanics. However, some supporting personnel such as airfield defence troops, weapons engineers and air intelligence staff do not have equivalent roles in civilian organizations.

s) to drop bombs on British cities. At that time, Britain did have aircraft, though her airships were less advanced than the zeppelins and were very rarely used for attacking; instead they were usually used to spy on German U-boats (submarines).
Fixed-wing aircraft at the time were quite primitive, being able to achieve velocities comparable to that of modern automobiles and mounting minimal weaponry and equipment. Aerial services were still largely a new venture, and relatively unreliable machines and limited training resulted in stupendously low life expectancies for early military aviators.
By the time World War II began, planes had become much safer, faster and more reliable. They were adopted as standard for bombing raids and taking out other aircraft because they were much faster than airships. The world's largest military Air Force by the start of the Second World War in 1939 was the
