Here's a big damn shuttle...or little damn ship for your spacefarers to explore their 'verse in.
And get into all kinds of trouble.
Obviously based on the Firefly/Serenity shuttle.
Only a bit simpler with low mounted fixed wings instead of the high swivel kind.
That's why I call it the FireBeetle Shuttle, Mark II.
