A closer look

Eurotunnel construction crews intentionally buried several massive tunnel boring machines directly beneath the English Channel rather than spending the time and money to extract them back to the surface. These colossal mechanical worms, each weighing hundreds of tons and costing millions of dollars, simply diverted their paths slightly downward after finishing their respective digging sections and were permanently entombed in concrete. There is something delightfully cynical about completing one of the most sophisticated engineering marvels in modern history and then just casually sweeping the gigantic, expensive digging equipment under the metaphorical rug. Future archaeologists will eventually dig them up and probably assume we worshipped giant subterranean metal deities, completely unaware that corporate accountants simply realized abandoning them in the oceanic bedrock was cheaper than paying return shipping
