Jet That Could Fly Across USA in One Hour to be Tested
Remember the Concorde? The supersonic airliner that flew across the Atlantic at 1350 miles per hour, making the ocean crossing in 3.5 hours, twice as fast as most commercial flights these days?
Imagine doing it in an hour, flying at 3600 mph (maximum speed). Or flying from New York to Los ...

Navy looks into UV cloak for stealth aircraft
The Navy's invested good money in the F-35 Joint Strike Fighter, which obscures radar waves and redirects engine heat to evade recognition by infrared sensors. But that stealth flier is still vulnerable to another type of detection: UV sensors. The Pentagon recently began soliciting proposals to develop a device that cloaks aircraft from ultra-violet detection systems. The hope is that such a technology could shield aircraft from missile seekers that scan the sky for telltale "UV silhouettes." According to the call for research, the solution could involve a device that disperses a cloud of quantum dots or other materials to veil jet fighters in a shapeless mass of UV shadow. Given that this is a rather daunting task, it's not surprising that the development timeframe and projected cost are still up in the air.
