The World's Longest Aircraft Is Half-Blimp, Half-Zeppelin

Unveiled last Friday, the Airlander is the world's longest aircraft. Developed by Hybrid Air Vehicles, the 302-foot-long Airlander was once a candidate military craft called "Long Endurance Multi-Intelligence Vehicle," until Pentagon budget cuts forced the U.S. Army to abandon the program.
The Airlander resembles both a blimp and a Zeppelin, but it's not quite either. Blimps have no rigid internal structure, while Zeppelins (technically, "rigid airships") have a stiff internal structure that holds the shape of the aircraft. The Airlander is, as the company name implies, a hybrid airship that gets lift from bags of helium. It has a rigid structure that offers more control than comes with blimps. To house the massive aircraft, Hybrid Air Vehicles is using a century-old airship hangar in Bedfordshire, England.
The U.S. military considered the Airlander for surveillance and cargo transport. Global Hawks and Grey Eagles, America's go-to surveillance aircraft, can each fly for about 30 hours. Fully stocked, the Airlander could stay in the sky for five days with a human crew. In wars where small armed groups move over vast rural areas, such as in the recent conflict in Afghanistan, a long-range surveillance tool is very valuable. While America's military involvement in Afghanistan is drawing to a close, Hybrid Air Vehicles is billing the Airlander as a tool for humanitarian relief, communications relay, border patrol, search and rescue, and drug enforcement. In addition to surveillance, the Airlander can be set up to carry 55 tons of cargo.

Flying Cameras At The Olympics


Here's a round-up of the week's top drone news, designed to capture the military, commercial, non-profit, and recreational applications of unmanned aircraft.

Targets, Tracked

Metadata+ is a smartphone app that alerts users to the time and location of drone strikes conducted by the United States. For each strike, it displays a brief sentence about the victims ("Tariq, 16, and Wahid, 12, were driving to pick up their aunt. A drone ended their journey.") and adds a pin to a drone strike map. The app's name comes from the peripheral information generated by communication, such as the location of a cell phone call, or the IP address for sending an email. According to a report published Monday by The Intercept, metadata is also the key way targets for drone strikes are detected.

Spelunking in Corvette Cavern

On Wednesday, a 40-foot-wide, 30-foot-deep sinkhole opened up at the National Corvette Museum in Kentucky. Eight Corvettes fell into the hole. To explore the pit, the University of Western Kentucky's engineering department wisely sent in a drone instead of a human. The Wall Street Journal obtained the video, which nicely skirts FAA rules against commercial use of drone photography. In the video, the drone's rotors are audible, and two of its legs can be seen. Also visible: a giant, scary sinkhole and a bunch of fancy cars.
