I know where "it" all went wrong! Some of them; Appllo 13 went wrong, Space shuttle Challenger went wrong, Iraqi war plans 2003 went wrong, King Harold battle plans 1066 A.D. went wrong, Roman supremacy went wrong, Hitlers supremacy went wrong, Amaco Cadis went wrong, Torre Canyon went wrong, car ferry Tricolor went wrong, car ferry Ferry of Free Enterprise went wrong. And you want answers why it went wrong?
Many others have asked me the same question over the years, and after much experimentation I can confidently state that the answer is:
In my kitchen, because I'm a truly appalling cook.
(The next question they usually ask is, where do you keep the Alka Seltzer?)
