The first milestone for UAS credited to Reginald Denny was which of the following?

• A. Mass produced UAS
• B. First remote-controlled aircraft
• C. Lightweight drone prototype
• D. Early reconnaissance drone

Answer: (A)

Reginald Denny’s milestone is about proving the concept of unmanned flight—making an aircraft fly without a pilot on board and guiding it from the ground. In the 1930s he demonstrated a radio-controlled aircraft, showing that flight could be controlled remotely. That breakthrough turned the idea of unmanned aerial systems into a real, workable technology and laid the groundwork for all later UAS development, including more capable drones and eventual production at scale. So, the key point is that remotely controlled flight was the first tangible step that made unmanned aircraft possible. The other ideas—mass production, a lightweight prototype, or an early reconnaissance drone—represent later stages or different facets of UAS evolution, not the initial milestone that established feasibility.
