Bubba applied for an engineeri...

Bubba applied for an engineering position at a Lake Charles refinery. A Yankee applied for the same job and both applicants having the same qualifications were asked to take a test by the manager. Upon completion of the test, both men only missed one of the questions. The manager went to Bubba and said: "Thank you for your interest, but we've decided to give the Yankee the job."Bubba asked: "And why are you giving him the job? We both got nine questions correct. This being Louisiana, and me being a Southern boy, I should get the job!"
The manager said: "We have made our decision not on the correct answers, but rather on the one question that you both missed."
Bubba then asked: "And just how would one incorrect answer be better than the other?"
The manager replied: "Bubba, its like this. On question #4 the Yankee put down; "I don't know." You put down, "Neither do I."

First concrete TV tower

In 1956, the world's first concrete television tower on the Hoher Bopser hill was inaugurated in Stuttgart, Germany, for Süddeutscher Rundfunk (now SWR). Instead of a steel girder transmitter mast, design engineers Fritz Leonhardt, Erwin Heinle and Rolf Gutbrod originated a 217-m steel-topped concrete needle to broadcast TV and FM radio. The observation decks three-fourths to the top provide tourists with views of Stuttgart, the local forests, vineyards and the Alps. It was built in 20 months at a cost of 4.2 million DM. Similar designs have since been used for many television towers around the world. The inauguration was attended by Anastas Iwanowitsch Mikojan, who later became head of state of the Soviet Union.«
