Two unusual aircraft are working their way through development and preparing to fly soon. The damage to the Airlander hybrid lighter-than-air cargo aircraft, sustained during a test flight last August in England, has been repaired, and crews are prepping it for another flight soon. While completing repairs, the company also made several improvements to the aircraft to reduce the chance of future mishaps. Meanwhile, the builders of Solarstratos, who aim for it to be the first solar-powered airplane to reach the stratosphere with a pilot on board, plan to start piloted test flights this month.
