"A Charlie Brown Christmas" Crossword Puzzle
December 6, 2015

A Charlie Brown Christmas - RF CafeIf you have been around RF Cafe or my hobby website, Airplanes and Rockets, for any length of time, you probably know of my being a lifelong fanboy of the Peanuts comic strip, drawn by Charles Schulz. This week's engineering crossword puzzle contains the names of many Peanuts characters who appear in the "A Charlie Brown Christmas" animated feature that first aired on TV on December 9, 1965, on CBS (all the other words are engineering and science related). Clues for those characters' names are marked with an asterisk. If you have never seen the show or if it has been a long time, there's no time like the present to watch it.

Reproduction of this puzzle without the express permission of RF Cafe is prohibited.
acr. = acronym, abbr. = abbreviation, pl. = plural, wds. = words
