Theodore Sturgeon was a prolific science fiction author who wrote many classic SF tales. One of them, More Than Human, should be mandatory reading for anyone thinking of writing an X-book.
Famously, there is also Sturgeon's Revelation: "Ninety percent of everything is crud."
But Killdozer isn't one of those things. The short story Killdozer 1st appeared in Astounding Science Fiction back in 1944. In the tale a WW II crew building an airstrip on a Pacific island fight their possessed bulldozer.
The very idea is a concept that hit popular cosciousness and it spawned a really bad tv movie with Robert Urich (somebody please tell me how a huge bulldozer could sneak up on people), a rock band and even a Marvel comic! Killdozer was also the name some media wits gave the modified bulldozer used in a sad 2004 feud between a business owner and the mayor and city council of some town.
Here's all the Killdozer I could find...
