The Physics of Flying at Mach 5

Fri, 16 Jan 2026 03:23:00 GMT

In this episode of Applied Curiosity, we dive into what really happens when an aircraft flies faster than Mach 5. At hypersonic speeds, air stops behaving like air, temperatures soar, shock waves form, and heat becomes the biggest enemy of flight. We explore how compression turns motion into fire, why shock waves cling to the aircraft, and how engineers try to survive inside this extreme physics. This episode breaks down the core science behind hypersonic flight in a way that actually makes sense.
