On the 18th of January 2019, an underground gasoline pipeline exploded in the little town of Tlahuelilpan, in the state of Hidalgo in Mexico.
The gasline was popular with thieves who, for years, had been drilling holes into it to collect gasoline for sale on the black-market. Mexico's new president cracked down on this illegal practice by placing soldiers and police here and there along the pipeline. This caused an increase in the price of gasoline.
So, when the pipeline sprung a leak on Jan 18th, 2019, presumably at a weak spot caused by an old drilling by gas-thieves, hundreds of people rushed to the scene with jugs, buckets, and containers of all sorts to collect fuel from the resulting geyser of gas. Soldiers and police were ineffective at holding back the crowd and were warned not to shoot anyone for fear of igniting the gas, so they simply pulled back and watched.
And they pulled back further when they noticed that dozens of people holding out their containers with one hand, held a burning cigarette in the other, or, in some cases, held one between their lips, actively smoking. As well, many of the hundreds getting free gas, and the clothes they wore, were getting soaked under the fountain of fuel.
Needless to say, a tremendous explosion occurred, followed by a tremendous fire that consumed all who stood within the immediate vicinity and severely burned people as far away as a few hundred yards.
PeMex, the Mexican state-owned petroleum company responsible for the pipeline, did not immediately shut the line off. Once the line was shut down, it took firefighters another 4 hours to safely extinguish the fire.
When hospitals in Hidalgo filled up, many burn victims were transported by medical helicopters to Texas.
This isn't a fun fact, certainly, but an interesting (if not harrowing) example of people's desperation, stupidity, and greed for free stuff at any cost.
