Did I do that?

Let me know your thoughts. Good or bad. I can take it. Most likely. Most often the answer from me is yea. My bad. Dropping your iPhone in the toilet is a stupid mistake... or a blunder... or you can call it an accident. But causing a planetary orbiter to burn up in space because you used the wrong math? Well, that's a little more of a blunder than that toilet incident. In just 20 minutes find out about some of the biggest boo-boos in the world. Thanks for list...
