The United States missed a year-end deadline for publishing new rules on remote-control aircraft, delaying an eagerly awaited step toward using drones in everything from farming to package delivery. Businesses have been clamoring for rules to allow commercial drone flights, fearing the United States is falling behind other countries in developing a multibillion-dollar industry. The Federal Aviation Administration turned a draft of the rules - the first major overhaul of the regulations - over to the White House on Oct. 23, and had said it expected them to be published in 2014.
