Carl Malamud sez, “This 1966 military film on good style in sending Morse Code is a real hoot. 38k views on YouTube and another 3.6k on the Internet Archive. This video was made possible by a crowd-sourcing appeal on Boing Boing in 2009 (and in the case of this particular DVD, a donation by Mary Neff … thanks Mary!)”
