New drone video out of Florida captured an aerial view of the devastation wrought by Hurricane Irma in the Sunshine State. The video, taken by Travis Long and posted by the Miami Herald Wednesday, showed Irma's path of destruction in Manatee County, south of Tampa on the west coast. The video showed enormous trees ripped out of the ground by their roots, roofs torn clean off homes and overturned and sunken boats. At least one person could be seen in the video working to restore a home amid the wreckage. President Donald Trump headed down to Florida Thursday to determine the extent of the damage left by the record-breaking hurricane.

This little drone captures and defeats rogue drones'Spiderman'-style. Just like how Spidey slings a web to capture bad guys, this little drone shoots a net to stop dangerous flying drones. Revealed this week at the Defence and Security Equipment International (DSEI) event, the world's largest defense and security show held biennially in London, this smart drone is already drawing a lot of buzz. Made by Dutch company Delft Dynamics, the DroneCatcher project is supported by the Royal Netherlands Marechaussee (Military Police), the Dutch National Police and the Dutch Ministry of Safety and Justice. The DroneCatcher is a multicopter – it has multiple blades and can shoot up vertically in the air, kind of like a tiny helicopter.

Deep sea explorers sent a drone to the ocean floor to beam back stunning images of the USS Indianapolis, a naval gunship that lies three miles beneath the surface of the Philippine Sea 72 years ago, in a dramatic live broadcast on Wednesday. Findings from the footage enabled experts to piece together the final moments of the WWII ship, which was discovered by Microsoft co-founder Paul Allen last month. The ship was sunk by a Japanese torpedo in the final days of World War Two, more than 18,000 feet below the surface of the Pacific Ocean, the Navy said. From the new drone footage, researchers have concluded that two Japanese torpedoes hit the ship, one of them striking an area near a chamber with crew members that likely would have died immediately upon impact. Researchers also discovered guns, torpedo remnants and parts of aircraft that were preserved thanks to the extremely cold temperatures at the bottom of the sea.

The term drone has become just another word for Unmanned Aerial Vehicle (UAV), even if the word originally implied fully autonomous flight whereas all known UAVs are still remotely managed or monitored by human beings.

This test shows progress for the team's first in New Jersey in 2016 (pictured) Johns Hopkins researchers set a new medical drone delivery record after successfully transporting human blood samples 161 miles. Among the two groups, the results for red blood cell, white blood cell, platelet counts, sodium levels, and other measures were all similar. 'We expect that in many cases, drone transport will be the quickest, safest, and most efficient option to deliver some biological samples to a laboratory from rural or urban settings,' said Timothy Amukele, assistant professor of pathology at the Johns Hopkins University School of Medicine and the paper's senior author. Among the two groups, the results for red blood cell, white blood cell, platelet counts, sodium levels, and other measures were all similar.

Two multi-million pound British Army drones crashed after taking off from a base in mid Wales, the Ministry of Defence has confirmed. The unmanned Watchkeeper aircraft were lost in the Irish Sea earlier this year, leading commanders to temporarily ground the entire fleet. Flight trials resumed at Aberporth Airport in Ceredigion in early July. The crashes are the latest in a series of accidents and delays to have hit the Army's new spy planes. The MoD ordered 54 Watchkeepers in 2005 as part of an £847m deal.

In three minutes, the Scout drone is assembled. One minute more, and it's airborne, tossed by a Marine. The flight is short, maybe 20 minutes at the most, but the information gained is valuable, a real-time video of just who or what, exactly, is behind that building a mile down the road. With the area surveilled, the aptly-named Scout drone flies back, and suffers a rough landing, snapping a wing. The squad can print another back at company HQ after the mission, and have it ready to go in a couple hours.

Jason Rowley is a venture capital and technology reporter for Crunchbase News. To the uninitiated, startup fundraising can be confusing. And even some of the resources designed to be approachable for the newcomer often raise more questions than they answer. So we've launched a series called "A Startup Takes Flight" to simply explain the dynamics of fundraising and deal terms. To do so, we're following two entrepreneurs who started a company and raised some money from investors.

The U.S. military carried out another round of drone strikes in Somalia Wednesday. A trio of drone strikes hit the Al Qaeda-affiliated al-Shabaab terror group killed six militants, U.S. Africa Command announced. The strikes took place 160 miles south of the capital, Mogadishu. They came after two separate drones strikes last week. Hundreds of U.S. soldiers have returned to Somalia for the first time since the "Black Hawk Down" incident in the early 1990s.

Wings are great for cruising over long distances and carrying heavy loads, but they aren't that great if your aircraft needs vertical agility. Rotors, on the other hand, are great for vertical agility, but they aren't that great for long distances and heavy loads. Any aircraft that wants to fly efficiently can be designed for cruising or hovering, but not both. Lots and lots of people have tried to figure out a way of making some sort of compromise work. Mostly, this involves stapling as many vertical rotors as you have a budget for to a fixed-wing aircraft and just calling it a day: When you want to go up or down, you use the vertical rotors, and the rest of the time, you use whatever other rotors you can afford to have mounted horizontally.
