National Aviation Day is being celebrated on Aug. 19 since 1939. Made through a proclamation by President Franklin D. Roosevelt, the holiday is observed to celebrate "all things aeronautical."

National Aviation Day is observed on the occasion of Orville Wright's birthday, who together with his brother Wilbur Wright completed the first "sustained flight of a heavier-than-air aircraft" in 1903.

Today, people can fly to many parts of the world thanks to the aviation industry. And this holiday is the perfect time to marvel at the power of flight and perhaps take a look back at how it has greatly evolved since aviation's early days.

People can celebrate the holiday by watching aviation-themed movies and documentaries or perhaps learn more about the science of flight. Some may also choose to spend the day "plane spotting" or building airplane models with friends or loved ones while those in the area may also visit the Wright Brothers National Memorial in Kill Devil Hills, North Carolina.

If one chooses to celebrate National Aviation Day, the point is to invite "appropriate exercises to further stimulate interest in aviation in the United States."

On this day, let's have look at some facts that may spark your interest in aviation. (Courtesy: KidsKonnect, BAA Training and National Today)
