Turbine-electric hybrid VTOL attack drone flies again

The Excalibur, a new turbine-electric hybrid propelled VTOL (vertical takeoff and landing) unmanned attack drone, has successfully completed another test flight after taking on two new onboard computers last week.

Developed by Aurora Flight Sciences Corp. for the U.S. Army Aviation Applied Technology Directorate and the Office of Naval Research, the Excalibur is another radical robo-craft concept vying to fill the military's burgeoning demand for specialized UAVs.

The demonstrator model, weighing in at 700 pounds, can hit 520 mph, making it one of the fastest drones around, according to the Aurora. The nearly autonomous flight control system allows operators to concentrate on finding and engaging targets instead of piloting the aircraft, according to the Manassas, Va.-based company. The Excalibur's jet-borne vertical takeoff and landing and three electric lift fans providing attitude control and hover thrust, make it "runway independent." After takeoff, it flies like a regular turbojet.

Why Twitter isn't pointless babble

Have you ever sat in a bar or a coffee shop, just watching what people do, examining the expressions on their faces, or just desperately trying to overhear the endearing nonsense that emerges from their mouths? That's how I think of Twitter.

Except there is one small difference with this peculiar little microblogging site: you can control who is in the bar or the coffee shop.

Some extremely clever people at Pear Analytics declared last week that 40 percent of tweets are "pointless babble". However, might their analysis be, as the English enjoy saying, just a little pear-shaped?
