Displays are getting personal. As soldiers join the network they need displays, and today's ruggedized laptops are heavy, power-hungry and breakable. The push is on to field lightweight, flexible displays that can be worn on the wrist or integrated into clothing or protective eyewear. The U.S. Army is testing wrist displays, and the U.S. Air Force kneepad touchscreens, produced by L-3 Display Systems using unbreakable plastic-backed organic light-emitting diode (OLED) technology from Universal Displays. These displays are small—only 4.3-in.

While privacy concerns bedevil efforts to integrate unmanned aircraft into U.S. national airspace, police departments across the country are pushing ahead with plans to field small unmanned aircraft systems (SUAS) operating under existing rules. The vehicle of choice appears to be a miniature rotorcraft, providing the ease of operation that comes with vertical-takeoff-and-landing and the ability to hover and stare. Canada's Draganfly Innovations has led development of the public-safety market with its 4.5-lb.

Commercial, government demand for broadband is driving market

After its unveiling of the J-20 and J-31 stealth fighters, it is not unimaginable that Beijing could pull off another technological surprise in 2013. Could it up the superpower stakes by testing an unmanned combat air vehicle, an air-launched strike weapon or even a mini-spaceplane? Speculation abounds.

Routine aircraft-like spaceflight operations could begin in 2013, with Virgin Galactic and XCOR Aerospace flying to the edge of atmosphere, but fully reusable air-breathing space access remains a dream. A crucial step forward could be tests of an air-breathing rocket engine component now underway in the U.K.

Bombardier's future as a major player in the passenger jet business could rest on its new CSeries aircraft. The first flight has been delayed from December until as late as next June, and a key Chinese fuselage supplier fell down on the job. In 2013, Bombardier needs the CSeries to fly and customers to buy. Chinese

Asian investors continue to take big stakes in the aircraft leasing market. A consortium of three Chinese investors plans to close on a deal to acquire the International Lease Finance Corp. That follows earlier sales of Jackson Square Aviation and the Royal Bank of Scotland's aircraft leasing business to Japanese buyers and Singapore Aircraft Leasing Enterprise's acquisition by the Bank of China.

Unmanned vehicles able to accompany troops and alleviate their loads have made a debut in Afghanistan, but if autonomous systems are truly to carry the burden they must be able to go wherever the soldiers go. Darpa's Agency's Legged Squad Support System (LS3) program aims to develop a four-legged robot that can carry 400 lb. and follow soldiers over rugged terrain, interacting like a trained animal with its handler. After initial outdoor trials early in 2012, Boston Dynamics is refining its LS3 for a U.S. Marine Corps field exercise in 2014.
