A high-tech, bullet-shaped aircraft with potentially revolutionary fuel efficiency could be getting closer to taking flight for the first time.
The pusher-propeller plane, dubbed the Celera 500L, was recently spotted undergoing taxi tests by NASA pilot Scott Howe, according to The Drive.
It's being developed by secretive California-based firm Otto Aviation Group, of which there are few known details.

'Strange aircraft sighting today on my #NASA #KingAir approach to Rwy-17,' Howe wrote in an Instagram post.
'This is apparently a Celera 500L, experimental pusher prop plane - #N818WM doing some high speed taxi testing. Very cool.'
N818WM references the plane's aircraft registration code, according to the Drive.
The tests were reportedly being conducted at the Southern California Logistics Airport in Victorville, which is northeast of Los Angeles.
The Celera 500L's 'exotic' design is all about increasing efficiency in aircraft performance, as well as making passenger air travel more seamless, the Drive reported.
Otto Aviation Group has filed several patents in the US with designs that closely mirror the Celera 500 L.

The tests were reportedly being conducted earlier this year at the Southern California
