When did the Army first test the feasibility of using paratroops?

The Army first tested the feasibility of using paratroops in September 1929. This date is significant as it marked the initiation of experimentation with airborne forces in the United States, highlighting the military's interest in how parachuting could enhance operational capabilities. The tests conducted at this time allowed for evaluations concerning the tactics, equipment, and strategy involved in deploying troops from the air, laying the groundwork for future airborne operations. The choice of September 1929 is critical as it is when these foundational experiments began, unlike other dates which do not represent the inception of these specific tests.
