Laurent Aigon, a waiter by trade, built his son a fully-functional flight simulator cockpit for a 737 in his room. The simulator was so accurate and well-made that it's attracted the attention of local pilots who use it for real training!
A team in Utah's Dugway Proving Ground sent what they thought were inactive samples to various other bases around the world for study before finding out they hadn't been properly irradiated before being sent off.
As NPR reports, the incident isn't as unlikely as you might think. The deadly substance is notoriously hardy and difficult to kill. With billions of potential spores to render inert via radiation, a 99.99% success rate isn't enough to keep samples from being potentially dangerous.
Luckily the threat has been contained and there's no risk to the general public, though surely someone's ass will be grass somewhere down the line...
