Airbus developing drones that can fly for 90 days straight

Airbus is developing a drone that can fly for up to 90 days straight.

The drones currently under construction have a wingspan of 80 feet, are able to fly at 70,000 feet and carry a payload of more than over 20 pounds. But the new models are estimated to be 35 feet larger and carry twice as much weight, the Telegraph reports.

The Airbus Zephyr already has the record for longest continuous flight at 14 days, the website said.
