For no apparent reason you are flying a spacecraft
around Chicago, through the sky above it, and
through the cellars and caverns beneath the streets.

You have a small amount of fuel, which can be
replenished from the 23 landing pads. For no
apparent reason, the pads disappear once you have
used them.
