Like most of you who love still and moving images, I was thrilled when the first drones started to come out. The first ones were quite expensive, shaky, and had poor image resolution, but things moved quickly. When I bought the DJI Phantom 2, the drone came equipped with 2K image resolution and superb stabilization—and has improved evermore.
A hypersonic missile is a rocket-propelled weapon that can travel faster than Mach 5 speed (1701.45 m/s), i.e. 5 times faster than the speed of sound (340 m/s). Some hypersonic missiles, typically powered by Supersonic Combustion Ramjets or Scramjet propulsion systems, are capable of reaching Mach 10 speed (3,400 m/s) and can travel up to 12,000 Km on board an ICBM.
