1976: CN Tower opens to the public
• Many European cities have tall telecommunications towers. Some are taller than the CN Tower, but are held up by wires. In other words, they are not "free-standing." • At 342 metres, the CN Tower has a glass floor and outdoor observation deck. There is a café and indoor observation deck at 346 metres, and at 351 metres there is a restaurant that rotates once every 72 minutes. The upper-level Skypod observation deck is 447 metres high.
• The original plans for the tower called for three towers linked together by bridges.
• Copper grounding wires were installed to protect the tower from lighting strikes. The tower is hit by lightning about 75 times a year.
• Almost two million visitors ascend the tower every year.
• The CN Tower's 102-metre communications mast was installed using a giant Sikorsky Skycrane helicopter nicknamed Olga. Olga's daily schedule was printed in newspapers so Torontonians could watch it in action. • The Sikorsky Skycrane was first built in 1963. It was a "flying crane" designed to carry payloads of up to 4500 kilograms. The U.S. Army used it in the Vietnam War to recover downed aircraft. • Sikorsky now manufactures the U.S. Army's Comanche and Black Hawk helicopters.
A few unusual CN Tower world records:
• 1980: Donn Reynolds yodelled from the Skypod roof for seven hours and 29 minutes
• 1984: Wearing pads, stuntman Roger Brown fell down 1760 steps in one hour and 51 minutes
• 1986: "Spider Dan" Goodwin climbed the tower's 335 metres of windows twice in one day
• 1999: Ashrita Furman of New York climbed up 1899 steps in 57 minutes - on a pogo stick
Also on June 26:
• 1945: The United Nations Charter is signed in San Francisco by 50 countries including Canada.
• 1990: The final report of the Dubin Royal Commission on drugs in sport recommends that Canadian athletes exposed as users of banned drugs be denied federal funding. The inquiry was launched after the 1988 Ben Johnson Olympic steroid scandal.
• 2000: One of the most significant scientific breakthroughs comes as researchers in six countries announce they have completed the working map of the human genetic code. The Human Genome Project decoded the 3.1 billion base pairs in human DNA, which will help identify the 60-100,000 genes in humans.
