The fastest serve ever recorded by a ping-pong player moved at about 70 mph (113 km/h). Professor Mark French of Purdue University's Mechanical Engineering Technology department and his graduate students, Craig Zehrung and Jim Stratton, have built an air gun for classroom demonstrations that fires a ping-pong ball at over Mach 1.2 (900 mph or 1,448 km/h). As the picture above shows, that's fast enough for the hollow celluloid balls to blow a hole through a standard paddle. Read More
GE Aviation is developing a revolutionary new jet engine that aims to combine the best traits of turbojet and turbofan engines, delivering supersonic speed capability and fuel efficiency in one package. Read More
- "Sometimes you have to go up really high to understand how small you are" – Felix Baumgartner, standing outside his capsule at an altitude of 24 miles (39 km) on October 14, 2012.
Wright Patterson AFB has confirmed in an official press release that Tuesday’s test of the Waverider X-51A unmanned hypersonic missile has failed. Launched from a B-52 bomber over Point Mugu Naval Air Warfare Center Sea Range at 11:36 AM PST, the separation from the bomber and ignition of the X-51A’s rocket booster went as planned. However, 16 seconds into the flight a fault occurred in one of the missile’s control fins before the scramjet could start and the X-51A was today officially reported as "lost." At present, there are no further official details, but the New York Daily News reports that the missile crashed into the Pacific Ocean while NBC News states that the X-51A broke up in flight and fell into the ocean "in pieces."

In the 1800s, when pneumatic tubes shot telegrams and small items all around buildings and sometimes small cities, the future of mass transit seemed clear: we'd be firing people around through these sealed tubes at high speeds. And it turns out we've got the technology to do that today – mag-lev rail lines remove all rolling friction from the energy equation for a train, and accelerating them through a vacuum tunnel can eliminate wind resistance to the point where it's theoretically possible to reach blistering speeds over 4,000 mph (6,437 km/h) using a fraction of the energy an airliner uses – and recapturing a lot of that energy upon deceleration. Ultra-fast, high efficiency ground transport is technologically within reach – so why isn't anybody building it? Read More
Recent days have seen reports emerge of a successor to Concorde capable of speeds of over 2,485 mph (4,000 km/h) that could fly from London to Sydney in a mere four hours. Read More
A throwback to early 20th Century aviation may hold the key to eliminating the sonic boom - at least according to researchers at MIT and Stanford University. Strongly reminiscent of biplanes still in use today, the researcher's concept supersonic aircraft introduces a second wing which it is claimed cancels the shockwaves generated by objects near or beyond the sound barrier.
