How does the 1784 Paris decree on balloon flights show the early development of air law?

The 1784 Paris decree is recognized as the earliest piece of legislation in air law. By requiring a special permit for balloon flights, this decree established a foundational precedent for state oversight of aviation.

It marks the early development of air law by demonstrating the immediate need for regulatory control over new flight technologies. Following the first successful manned balloon flights in 1783, which captured the public imagination, authorities recognized that the ability to navigate the atmosphere necessitated legal frameworks to ensure public safety and order. This early intervention by the Paris police serves as the historical starting point for the comprehensive body of civil aviation regulations that govern heavier-than-air and lighter-than-air aircraft today.123
