The Loudoun County Sheriff's Office says said it took just 20 minutes for the drone to find the missing hunter on Sunday morning. A search team on the ground was then able to go help the man, who they said was found without injuries.

The US military has used drones in combat zones for over a decade to scout and support infantry. Now they're testing a way to give ground troops another edge: The capability to build UAVs themselves. What's more, the US Army is partnering with the Marine Corps on a test project that lets troops 3D-print particular drone parts from a tablet-based catalog, which could eventually lead to manufacturing UAVs customized to the mission. The concept is promising, and so is the flexibility: The software catalog setup lets military units print out an unmanned aircraft system for specific missions. The Army Research Laboratory expects the turnaround time to create UAV parts to be from minutes to hours.

Walmart has submitted a patent application for a drone delivery system that focuses on how packages will be received. Instead of just delivering goods to your doorstep, drones would drop packages into secure boxes (lockers) that communicate with the drone. The application describes a smorgasbord of technology that could be used to ensure secure drop-off, including geofencing and a blockchain for package tracking and identification. Just like most patent applications, Walmart's "Unmanned Aerial Delivery to Secure Location" is jam-packed with redundant language, ambiguous line drawings, buzz words, and ample legal jargon. Still, the basic premise is clear: a delivery system that includes a robotic vehicle that communicates with a secure locker.

Democratic Gov. Andrew Cuomo announced the deployment on Thursday. The nine airmen are all members of the 174th Attack Wing. They include pilots, sensor and camera operators and image analysts. The teams will use drone surveillance to capture up-to-the-minute information on the fire's location to allow for better placement of fire personnel.

The Los Angeles Fire Department dispatched drones for the first time while battling a wildfire this month as firefighters took on the Skirball fire in Bel-Air. Fire officials demonstrated the use of the unmanned aerial vehicles for reporters on Thursday, sending two drones buzzing near blackened hills around Linda Flora Drive. "They provide real-time situational awareness from a bird's-eye perspective to the incident commander so they can see what's going on at their emergency and then change their tactics accordingly to mitigate the hazards," said Capt. Firefighters used two DJI Matrice 100 drones during the Skirball fire, Scott said. One had a high-definition camera used to survey the burn area, and the other had an infrared camera to assess hot spots.

WASHINGTON – A recreational drone operator was at fault in the first confirmed midair collision in the U.S. between a drone and a manned aircraft, the National Transportation Safety Board said Thursday The operator was unaware the Federal Aviation Administration had temporarily banned drone flights in New York when his small drone collided with an Army Blackhawk helicopter on Sept. 21, the board said in a report on the incident. The U.N. General Assembly was meeting in New York at the time. The helicopter suffered minor damage while the DJI Phantom 4 drone was destroyed, the report said. The operator flew the drone 2.5 miles away despite a long-standing FAA prohibition on drone flights beyond the sight of an operator, the report said. The operator saw the helicopter on the tablet he was using to direct the drone and tried to move the drone out of the way, but it was too late to avoid the collision, the report said.

Remember back when you could fly drones without having to pay the government money first, and when the only thing you had to worry about was a midair takedown by an anti-drone hit squad made up of highly-trained Dutch eagles? We're sad to have to report that we probably won't be seeing compelling videos of eagles handling rogue drones anymore, and also that the United States government has flexed its muscles and mandatory drone registration is now back on. You probably remember how the FAA finalized its mandatory drone registration rules just in time for the holiday season in 2015. Any drone that weighed more than 0.55 pounds was required to be registered before being flown outdoors, a process that involved providing your complete name, physical address, mailing address, email address, and a credit card that was charged a one-time fee of US $5. In exchange, you got a unique registration number that had to be visible on all of your drones.

WASHINGTON – Federal investigators say a recreational drone operator was at fault in the first confirmed midair collision in the U.S. between a drone and a manned aircraft. The report says the operator was unaware the Federal Aviation Administration had temporarily banned drone flights in New York when his drone collided with an Army Blackhawk helicopter on Sept. 21. The U.N. General Assembly was meeting at the time. The helicopter suffered minor damage while the drone was destroyed. The report said the operator flew the drone 2.5 miles away despite an FAA prohibition on drone flights beyond the sight of an operator.

Earlier this year, the FAA and U.S. Interior Department separately barred drone flights within the boundaries of sites including the USS Constitution in Boston, the Gateway Arch in St. Louis and Independence National Historical Park in Philadelphia. The list also includes Glen Canyon Dam in Arizona, Hoover Dam in Nevada and Grand Coulee Dam in Washington state.

The 4,500-year-old secrets of the Great Pyramid of Giza's maze of hidden chambers are set to be revealed by an inflatable robot. Researchers are building a blimp-like probe that enters ancient monuments via a 3.5-centimetre (1.4-inch) 'keyhole' drilled through a wall. Once inflated inside the chamber, the drone flies like a blimp to explore inaccessible areas with minimal damage to artefacts or structures hidden within. Last month, a mysterious 30-metre (100ft) void nestled above the pyramid's Grand Gallery deep within the monument was discovered by an international team of researchers.

It is made up of two robots, a tubular machine equipped with a high definition camera and a probe that explores the structure via a small, inflatable blimp.
