A regular addition to cellphones and bank cards, radio frequency identification (RFID) tags are creeping into airplane cabins. With tags in life vests, seats, medical kits, and other frequently inspected equipment, attendants can cut down inspection times tenfold, saving money and improving plane turnarounds.
Carbon fiber is much stronger and stiffer than aluminum. Boeing's 787 Dreamliner was the first airliner to use a predominately carbon-fiber airframe. The Airbus A350 will join it this summer. The lighter frames allow increased fuel efficiency, and a stronger fuselage allows more comfortable cabin pressures.
Batteries are little black boxes of chemistry, and when they fail, it can be hard to diagnose the problem. Scientists at PARC have embedded batteries with fiber-optic sensors. With internal data, engineers could optimize performance in real time or pinpoint the source of a problem to fix the trouble in future designs.

That tiltrotor concept looks strikingly similar to a certain craft in a game I played. Hmmm...
rfid tags are electromagnetic fields,which they always tell us are bad for airlines,turn off your electronics,and the fire on the Dreamliner showed holes in plane if it had been in the air,pressure would have made it worse,i also wonder about turbulence on plane wings for 20 years which will stand up better,will carbon just break off,as for sensors on Dreamliner,they don't seem to working as the batteries are getting over charged and going on fire
Was the self flying drone not an advancement in aviation, I guess when you have made as many simulation flight as they would have, the real thing isn't so exciting...
No. 1: United States
Military expenditure: $668.8 billion
Expenditure as pct. of GDP: 4.4%
One-year spending change: -6.0%
Total exports: $6.2 billion (the highest)
Total imports: $670 million (6th highest)
The United States spends more on its military than any other country by a wide margin. America's military budget accounts for roughly 40% of all military spending in the world, according to SIPRI. However, U.S. military spending has declined since 2010 -- when it hit more than $720 billion -- largely due to a reduced presence in Iraq and Afghanistan.
The United States is by far the largest arms exporter in the world, selling more than $6.2 billion worth of arms in 2012. In June, the White House announced it was arming the opposition against Syrian President Bashar al-Assad's regime.
for FY2012 the US DoD budget was less than $600B, which was less than 16% of the total US federal budget.
I believe most (if not all) future VTOLs will be based off of this design:
AgustaWestland's Project Zero basically is a VTOL plane that has tiltrotors built into the wings, meaning the whole outside of the wing doesn't move as with the Osprey, rather only the rotor tilts.
Batery sensors? Hey tell Boeing.
