I mentioned several. Which is this one that nobody knows?

Bastable? Bastable comes from the period and an alternate
timelime of Mrs. Amelia Underwood. The Bastable stories were
in the old Ace style dime novels around 1976... short novels,
not really stories. He's an airship captain in the alternate
timeline where nuclear technology was never invented.

I used to make a steady diet of this stuff: Phil Farmer, Sturgeon,
and the ace of pulps Ron Goulart. I still listen to the old
time radio stories when they're on like "X Minus One." And there
is some current news about Norman Corwin -- like a retrospective--
but I lost track of that.
