Facebook has completed a second test of a solar-powered drone named Aquila.
Facebook has designed Aquila to bring internet access to remote parts of the world.
The aircraft flew for 1 hour and 46 minutes, and landed perfectly on the prepared landing
site in Arizona.
Aquila's second test flight took into account the lessons Facebook learned from their first
flight which was crash-landed.
This time, the drone flew at an altitude of 3,000ft
By design, Aquila does nothing fast: It climbs slowly, descends even slower, and when flying
upwind moves only at 10-15 mph over the ground.
Facebook designed Aquila this way because it is meant to stay in the same area for long
periods of time to supply internet access.
Aquila is solar-powered and extremely power-efficient —- running on the power equivalent of three
blow dryers.
