Now a new crop of students has gone back to the drawing board—with hovercraft plans published in Popular Mechanics in 1971. “We’re making great progress,” teacher James Benini says....

We like to showcase the positive outcomes of humanity’s inexorable march of progress, like ever taller skyscrapers and novel gadgets. But it’s also important to remember the other side of that coin; all the strip-mined land and leftover scrap that was necessary to get where we are today.Take, for instance, this drone video of an abandoned quarry. At some point, this quarry was part of a pristine forest, but now it’s just bare land, dotted with a few rusted buildings....

Stories of Nazi super weapons have persisted since World War II, and although these are mostly fiction, they can make it seem like only the Axis had wild ideas. Not so!

The site traditionally included accident data per type of aircraft—AV-8B Harriers or F/A-18C Hornets, for example—daily accident summaries, and general accident statistics....

A radio satellite survey has detected the remnants of two previously unknown supernova explosions.Found in the Small Magellanic Cloud, the scientists hope the discovery is just the beginning for their survey over the next five years. Based in Australia, their telescope imitates a bug’s eye to get a deeper view of the universe. Studying a nearby galaxy known as the Small Magellanic Cloud (SMC), scientists from the University of Manchester found something haunting: remnants of two possible supernovas, the cloud of gas and dust left over after a star explodes....

The Pentagon has dispatched four B-52 heavy bombers to the Middle East, in response to an alleged Iranian threat against U.S. forces in the region. The purpose of the deployment, whether to deter an attack or pre-empt one, is unknown. Although six decades old, the B-52’s heavy weapons load and long legs ensure that when a crisis erupts it is Air Force’s go-to heavy bomber.According to CBS News, four B-52H Stratofortress bombers took off from Barksdale Air Force Base in Louisiana and are expected to land at Al Udeid air base in Qatar later today....
