The jeep was a crazy amazing brand new machine. The media which consisted of the printed word (newspapers), radio and movies. You can see pictures of jeeps “flying” through the air. The drivers must have been a wee bit crazy. But I think in the case below it is a staged photo capitalizing on the jeep mania.
Check out Jeep – Its development and procurement under the Quartermaster Corps, 1940-1942 for all the “lurid” details about the jeeps beginnings. It’s a great read, written during the war.
