On the left is the fully-reusable
X-33.
It will make its first
test flight in July of 1999, but isn't big enough to fly all the way
into orbit. It's the prototype for the big one in the middle,
which will be the first commercial space shuttle. Private industry
will build and fly it, sometime early in the 21st century.
I've been waiting for this since I was six years old...
