I have always been impressed that pilots can control aircraft's by operating the directional flight controls.
I don't really know much about flying planes. What type of schooling or training is required to be a pilot?
I am not sure, but I think it is 500 hours of flying so they can be safe.
How long does it take  in classroom time to get a basic license? Are there different levels?
Again I am not sure, I do know that you can do a pay to work program so you can operate an aircraft by paying for it.
Who oversees pilots, Is there an aagency?
The Us airline pilots association is the agent for the US airways, and they get involved when they need an agent.
Do you know anything about the requirements to be a steward or stewardess?
Aircraft pilot
An aircraft pilot or aviator is a person who controls the flight of an aircraft by operating its directional flight controls. Some other aircrew members, such as navigators or flight engineers, are also considered aviators, because they are involved in operating the aircraft's navigation and engine systems. Other aircrew members, such as flight attendants, mechanics and ground crew, are not classified as aviators.
In recognition of the pilots' qualifications and responsibilities, most militaries and many airlines worldwide award aviator badges to their pilots.
, "It never really was me." In 2006, Earnhardt told Dan Wetzel of Yahoo! Sports: "We live in a country where you can speak freely and do as you may. I don't know (if) what that flag stands for is the same for me as it is the guy who might have it flying out there. I am not going to agree with everything everybody does all my life. So I don't have any control over it." Following the Charleston church shooting in 2015
