I managed to land my inter-planetary jet on the mun.

It's just a jet with retractable landing gear. No other stages or anything.
I flew it to the mun but when I got there it hit me that I might break my thruster off if I try to land on it, so what I did was jetted up really quick before I hit the ground and turned 90 degrees flat on my landing gear and it worked.
As you can see here, there are no extra stages whatsoever.

EDIT:
I took off from the moon (with the help of a little hill. :3)
Holy crap I actually managed to land at the space center!

Kinda broke off my engine in the landing...but I didn't need it anyway!

And with just barely any fuel left. :3
