LE BOURGET, France (AP) — While Airbus and Boeing will again hog the spotlight at the Paris Air Show with their battle for ever-larger slices of the lucrative pie in the sky, a lot of the really interesting stuff will be going on elsewhere at the upcoming biennial aviation and defense industry gathering.

Lockheed Martin’s F-35 jet will crane necks with high-speed aerial displays, drones will again be a hot topic and a would-be flying car will aim to show that it is closer to getting off the ground as a consumer ride. Defense contractors will be seeking customers for their latest high-tech weapons, including drones designed to act as wingmen to piloted aircraft in battle.

More peacefully, there’ll be the launch of a distress beacon with an integrated GPS transmitter to help locate planes that go down — an issue of vital importance after the failure to locate Malaysia Airlines Flight 370 that disappeared with 239 passengers and crew on March 8, 2014. And several companies are showcasing technologies to allow passengers to stay connected in the air.

With airlines suffering a string of public relations’ embarrassments recently — from the United Airlines’ passenger getting dragged off a flight to British Airways’ massive outage — the aerospace industry is eager to show off its goods.
