During the B-29 raids on Japan in WWII the Japanese would draw chalk outlines of B-29s, seemingly trailing smoke from one or more engines, onto fields, then surround those fields with AAA batteries. Goal was to lure other B-29s down to provide assistance to their "stricken" comrade, then shoot them down.
