Many of the words in this week's crossword puzzle pertain to radar engineering. All the rest of the words are related
to technology, engineering, science, mathematics, aeronautics, ham radio, chemistry, etc. There are no names of Hollywierd
actors, shoe designers, or romance novel titles. Enjoy.
I will be glad to create a special edition crossword for your newspaper, newsletter, etc.
