#95: Chunnel Blunder
In 1990 the News of the World reported that the Chunnel project, which was already suffering from huge cost overruns, would face another big additional expense caused by a colossal engineering blunder. Apparently the two halves of the tunnel, being built simultaneously from the coasts of France and England, would miss each other by 14 feet. The error was attributed to the fact that French engineers had insisted on using metric specifications in their blueprints. The mistake would reportedly cost $14 billion to fix.
