I made the side windows from sheet styrene, some clear plastic from packaging material and fine screen. They are just loosely plugged in for now.

The rear “window” was a piece of unfinished dirty plywood. ( The clear plastic window turned white, cracked and ultimately fell out within a couple months of owning it.)
There was a silhouette of the Stealth Bomber left from when I painted a model of one on the wood (when the B2 was still somewhat classified). The Kammback script was a leftover badge from my Vega.
