Rolls-Royce Electric Plane To Achieve 300 Miles Per Hour! Spirit of Innovation Aircraft Completes a New 15-Minutes Flight Test
Rolls-Royce electric plane, Spirit of Innovation, completes its latest flight test. The company now enhancing it to achieve 300 miles-per-hour speed.
SR-71 Blackbird, Americas
The SR-71 made good use of the engines; its top recorded speed was 2193 miles per hour.

No manned aircraft in operational service has matched the remarkable long-distance Mach 3 cruises of the Blackbird.
Here's What You Need to Know: The SR-72 depicted in Lockheed’s concept art was described as capable of cruising at six times the speed of sound.
Hypersonic weapons—those capable of flying over five times the speed of sound—are the hot new buzz word of defense industrial complexes across the globe. China, Russia and the United States have all...
