Steam aircraft were unusual devices because of the difficulty in producing a powerplant with a high enough power-to-weight ratio to be practical. They are distinct from airships that use steam as their lifting gas which are known as thermal airships.

Famous quotes containing the word steam:

    The windows were then closed and the steam turned on. There was a sign up saying that no one could smoke, but you couldn’t help it. You were lucky if you didn’t burst into flames.
