"Great strides have been made in aviation since Orville Wright's
first flight in 1903. Today, general aviation aircraft range from
light sport aircraft like the Piper J-3 Cub to personal jets like
the Eclipse 500. In America, we also have a unique freedom that
keeps GA efficient and affordable, so we certainly have many
reasons to celebrate National Aviation Day."
