A steam aircraft is an aircraft propelled by a steam engine. 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:
“A steam ran small and terrible and shrill;
it was so still;
the stream ran from the oak-copse
and returned and ran
back into shadow.”
—Hilda Doolittle (1886–1961)
