Barnstorming is an activity in which a pilot performs aerial stunts, usually for entertainment or promotional purposes. It was popular in the early days of aviation, when pilots would fly to small towns and perform stunts such as loop-the-loops and low-level flying. Barnstorming was a way for pilots to show off their skills and make money at the same time. The term 'barnstorming' comes from the fact that pilots often landed in farmers' fields and barns. Performing aerial stunts is a form of barnstorming, and it is still practiced today.
