Is there a recognized boundary between airspace and outer space?

• A. Yes, it is clearly defined
• B. No, there is no formal agreement
• C. Yes, universally accepted at the Kármán line
• D. No, but it is generally accepted at 100 km

Answer: (B)

The concept of a boundary between airspace and outer space is a subject of discussion and debate, and currently, there is no universally recognized and formal agreement defining this boundary. While there are various proposals and definitions, the absence of a definitive international treaty means that countries may apply their own criteria for distinguishing between airspace and outer space. Option B reflects the reality of the situation: there is no formal agreement that provides a clear and universally accepted boundary. In practice, the distinction may vary based on national legislation and policy, often leading to inconsistency in how different regions and states classify these domains. The idea of a demarcation line remains an area open to interpretation and diplomatic negotiation rather than a settled international standard. While other options mention either the Kármán line or a general acceptance at 100 km, these do not convey the lack of formal recognition effectively, as there is no binding definition that universally applies to all nations.
