Loon Copter is a drone that can fly and go underwater


The first prototype of the Loon Copter was tested in early 2015; a newer iteration is a semifinalist in the UAE Drones for Good Award, a competition whose finals are held in Dubai in early February.
Possible uses for such a versatile drone are many, including reconnaissance as well as search and rescue missions. Its advantages over traditional vehicles are many; for example, it's faster than a submarine and it can easily hover over an area of interest.
There's also room for improvement. The Oakland University team says priorities include extending wireless range underwater, underwater navigation and hull redesign for more efficient diving.
