An English proverb rightly states, "to err is human; to forgive, divine.”
Just like this, there have been several mistakes made by people in the past that have changed the course of today's world. While some blunders have completely changed the course of history. Here is a list of such important blunders, some intentional which have changed the present world.
1. A key could have saved the Titanic from sinking:
The life of around 1500 people could have been saved if an officer had remembered to give the keys to a room to his substitute. Second officer David Blair was transferred from the ship and had forgotten to give the keys to the room that had binoculars. The life of so many people could have been saved only if Officers had access to binoculars on the bridge or in the crow’s nest.
2. A man threw away a $181 million lottery ticket:
Fortune struck big for a Brit lady, who almost won a lottery worth $181 million, but her husband threw the ticket in the bin. “I play every week - I play the lottery, the Euromillions, and the Thunderball - but my husband takes the ticket from me and I don't see it again. That's why I always write my numbers down," News.com.au quoted her as telling the Coventry Telegraph. The winning ticket was netted as the biggest jackpot ever scooped on the Europe-wide contest.
3. NASA lost a $125 million orbiter in space:
Yes we even have NASA on the list, NASA lost a $125 million Mars orbiter because a Lockheed Martin engineering team used English units of measurement while the agency's team used the more conventional metric system for a key spacecraft operation. A big blunder. After all of this Tom Gavin, the JPL administrator to whom all project managers report said,” "People make errors."
4. Lost World War 1 because of a rumor:
Famously termed as “Russian Rumour”, it was series of misunderstandings on the part of German soldiers. Soldiers reported that they were from Ross-shire, a German misunderstood them and heard it as heard it as 'Russia'. He spread the word that they had come to attack. Because of this Germany changed its course of attack and strategies with the aim to stop their enemies and win the war.
5. Piper Alpha oilrig explosion:
It happened on 6 July 1988 off the coast of Aberdeen and ended up killing over 160 people. The incident took place because there were many lapses in safety inspection and procedures. Its loss was of $3.4 billion in total and is still the world's deadliest ever oil rig accident. The event that triggered the initiation of the explosion was when a worker forgot to screw a safety valve back on the ship which led to a gas leak.
6. The biggest wildfire in California:
The tragic incident that took up over 300,000 acres of forest and nearly destroyed 2300 homes is one of the biggest wildfires in California's history. The incident costs a whopping $1.2 billion and was just because a hunter lit a signal match flare.
