After graduating from the USAF Metrology School, individuals would be assigned to Base Precision Measurement Equipment Laboratories (PMELs) throughout the world. At one time there were as many as 2,000+ PMEL members working in laboratories from the remote Aleutian Islands and other equally as desolate locations to plush assignments in the USA, Asia, Europe, Middle East, as well as elsewhere around the globe. Given that the Internet had not yet arrived on the scene, a way evolved to keep in touch with each other at least annually through the PMEL “Christmas Card,” usually hand crafted and reproduced on 8.5" x 11" standard letter-sized paper and mailed to each lab around the world. In this way, we would know who was where, who was being reassigned, where they were headed, and who the new arrivals would be to fill their slots. Here's a sampling of those cards.
