What is this Thing?

Sorry today's brick is late; I had a busy day today, and didn't get a chance to sit down at my computer until this evening.
---Today's Brick---
Name: Unknown
Size: 6 wide, 10 deep, 5 high

Honestly, I don't know what the name of this piece is called. I'm also not sure what, if anything, it was originally made for. It looks like it could be used as the cockpit of a spaceship, since it has a mounting point for a hinge piece:

In the above photo, there is a green hinge piece on the mounting point.
If you want, you could also use this piece as a spaceship all by itself. The back even has places where you could mount rocket engines:

I bought one of these at the Lego store, just for the heck of it. Now I should find some way to use it.
