First air-breathing, liquid fuel-powered scramjet takes flight
Before the sun had even risen over Wallops Island, Va., on 10 December 2005, a joint Office of Naval Research/Defense Advanced Research Projects Agency vehicle achieved a world first. At an altitude of 63,000 feet, the Freeflight Atmospheric Scramjet Test Technique (FASTT) vehicle became the first air-breathing, liquid hydrocarbon fuel-powered scramjet engine to fly.
After launching from the NASA Wallops Flight Facility on a two-stage, Terrier-Orion unguided solid-rocket system, the approximately 106-inch long, 11-inch diameter, missile-shaped vehicle raced at 5,300 feet per second (Mach 5.5) for 15 seconds before a controlled splashdown into the Atlantic Ocean. The FASTT vehicle project is part of the joint ONR/DARPA Hypersonic Flight Demonstration (HyFly) program and is designed to demonstrate low-cost flight test techniques and obtain in-flight engine performance data at hypersonic speeds. The overall goal of HyFly is to flight-test key technologies enabling a long range, high-speed cruise missile that can cruise at speeds up to Mach 6.

Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.
The vacuum is not empty. It may sound like magic to laypeople but it has occupied physicists since the birth of quantum mechanics.
