Previous Year Question
What is ‘Greased Lightning-10 (GL-10)’ recently in the news?
Electric plane tested by NASA
Solar-powered, two-seater aircraft designed by Japan

Reusable rocket designed by ISRO
Correct Answer: A
Detailed Solution
Greased Lightning-10 or GL-10 was an experimental, remotely piloted electric tilt-wing aircraft developed and tested by NASA.
GL-10 had a total of 10 electric motors—eight on its wings and two on its tail.
It could perform vertical take-off and landing (VTOL) like a helicopter.
During flight, its wings and tail rotated, enabling it to transition from helicopter-like hovering to more efficient forward flight like a fixed-wing aircraft.
It was used to test distributed electric propulsion, low-noise operation and more efficient VTOL aircraft technology.
It was not a passenger-production aircraft but a NASA technology demonstrator.
