4 Every engineering project has its ups and downs, and the development of unmanned High Altitude, Long Endurance (HALE) aircraft has seen its share of both. One of the most high profile developments, the Aquila system developed in the UK for Facebook, was put into a terminal tailspin last month when the project was cancelled. The system was an ambitious design that aimed to put an internet base station into the sky at 70,000 ft, connecting to the ground as well as other craft in the air. This connectivity proved to be the killer for the project. A similar problem with communication hit Titan Aerospace, which was bought by Google in 2014 and closed down two years later. At the same time, Airbus has been quietly working on its own project. The Zephyr UAV started life in 2003 and the latest version, the Zephyr S, is now entering production – the first HALE system to do so. It is aimed at long-term surveillance, carrying a high-resolution camera up to 70,000 ft and feeding images to the ground (see Platform One). The lightweight craft gets its power entirely from solar cells and can stay up for a month at a time. The production plant is named after the founding engineer, Chris Kelleher, who died in 2015. The serial production of his original design is a fitting tribute to the skills and persistence of the engineers who are pushing the limits of the technology.
