Ever wondered how jets are tested to be sure they'll stand up to stress? No, I can't say I have either. But apparently, the test is done by broadcasting baa baa black sheep and other nursery rhymes at high volume in a special test chamber. Why? Because one day, a technician got bored. It was originally done simply using a number of different frequencies, but after testing the aircraft fully, the technician decided to hook a microphone into the system. Testing testing worked just fine, but singing baa baa black sheep caused the wheel to fall off the jet. So now (according to my dad anyway, but he assures me that the person who told him this wasn't pulling his leg), the US military sings nursery rhymes to their jets to make sure they won't drop apart.
It's possible to make a computer crash... by rattling a plastic bag with coins in it over the keyboard.
On a Sunday afternoon, a bunch of air traffic controllers in Scotland managed to put their machine out of order for several months. They were having a competition to see who could push the most buttons at once.
Can you tell my dad's an engineer?
