Today’s Saturday Stumper

The work of “Garrett Estrada” and “Ernesto G. Prada” made me wonder if this week’s Newsday Saturday Stumper would reach some greater height of difficulty. No soap. Today’s puzzle, by Lester Ruff, was pretty simple stuff.

A few clues that I thought novel: 15-Across, nine letters, “Climbed all over.” 20-Across, six letters, “With integrity lost.” 41-Across, four letters, “An aerophone.” 38-Down, eight letters, “Trying inductions.” 50-Down, six letters, “Clears for the road.”

No spoilers: the answers are in the comments.
