Thanks for reminding me of Ab Doble, onetrack.
As a follow-on from his work, the Besler brothers successfully converted and flew a steam-powered Travel Air 2000 at Oakland, California in 1933.
A civilised way to go, I think.
Y'see, while one is waiting for the boiler to warm up, it affords the opportunity to partake of tea and crumpets while having another look at the met forecasts
and, if necessary, review one's flight plan.
Besides, NVH is all but eliminated - further adding to passenger amenity.
