Preparing to launch - what goes up, no longer necessarily needs to come down - at least not for a very, very long time
Zephyr, QinetiQ’s solar-powered, high-altitude long-endurance (HALE), Unmanned Air System (UAS) is currently in the air and setting a landmark unmanned flight duration record by demonstrating what is essentially perpetual flight. The official world record for the longest unmanned flight is 30 hours 24 minutes set by Northrop Grumman's RQ-4A Global Hawk in 2001. A previous smaller relative of the current Zephyr holds the unofficial record of 82 hours but this time QinetiQ has FIA officials on hand and has been flying the new 22.5m wingspan plane for the past week, and is closing on the 200 hour mark with another week (168 hours) planned. It needs to land safely to claim the record, but the feat has already demonstrated that the era of low-cost, persistent aerial surveillance has begun.
