The 'Jet Fuel Can't Melt Steel Beams' meme originated from the 9/11 Truth movement, where it was used as a serious argument regarding the structural collapse of the World Trade Center. However, around 2014, it underwent a massive transformation in internet culture, becoming a satirical non-sequitur used to mock conspiracy theorists. The phrase is now commonly used as a punchline to derail serious discussions or as a caption for absurd images that have nothing to do with the original event. It stands as a prime example of how the internet can turn a controversial political statement into a versatile piece of ironic humor.
