There have been several epic man-made errors throughout history that have had significant consequences. Here are a few examples:

Chernobyl disaster: The Chernobyl nuclear power plant disaster in 1986 was caused by a combination of human error and design flaws. The explosion and subsequent radiation release killed 31 people directly and resulted in long-term health effects for thousands of others.

Deepwater Horizon oil spill: The Deepwater Horizon oil spill in 2010 was caused by human error and equipment failure during drilling operations. The explosion killed 11 people and resulted in the largest marine oil spill in history, with devastating consequences for the environment and local communities.

NASA Challenger disaster: The NASA Challenger disaster in 1986 was caused by a failure of an O-ring seal due to low temperatures, compounded by management decisions that disregarded safety concerns. The explosion killed all seven crew members and led to a reevaluation of safety procedures and organizational culture at NASA.

Volkswagen emissions scandal: The Volkswagen emissions scandal in 2015 was caused by deliberate manipulation of emissions testing software to deceive regulators and consumers. The scandal resulted in a $30 billion settlement and significant reputational damage to the company.

These examples illustrate the importance of learning from man-made errors to prevent future incidents and improve safety, accountability, and ethical practices in all areas of human activity.
