In case there was any doubt he's a walking angel among us, Chesley Sullenberger has done penance for being overdue on a library book stuck in that plane he safely landed on the Hudson River.

Oh, good, because it just wasn't enough he politely requested an extension on the book, or that the volume was about "professional ethics," or that he saved 100+ lives and then advanced journalism education and then made America swoon.

No, he had to go and make a video for the San Francisco Public Library — Sullenberger lives in Danville, right across the bay — about the "fine amnesty" program, May 3-16. Even though the guy will soon have a book to sell, so library use won't exactly help his bottom line.

Sully is like remedial Mr. Rogers, for adults. And most of us would benefit from a few episodes.
