Another important method is one-sided glass. This is really neat, because you can only see through it one way. No one is sure how this works either. A popular style of window used for religious or decorative purposes is stained glass, which combines pieces of colored glass in such a way as to produce a pattern or picture. Unfortunately, stained glass can rarely be seen through.
Windows are also significant when broken.
Often children are responsible for this. Occasionally, however, some irresponsible pilot breaks a certain thing called the sound barrier, causing another thing called a sonic boom, which can shatter windows. Broken glass contains sharp edges and can be quite painful if jabbed into any part of the body. I find windows to be quite attractive and all together more useful than quite a few other things, like chickens. This Project Galactic Guide site owned by Alex McLintock .
