View from the Glass Floor at CN Tower in Toronto. I stood here on the glass and hope that nothing will break!!! (scanned from a negative)

The CN Tower, at 553.33 metres (1,815 feet, 5 inches) tall, is the world's tallest freestanding structure on land. It is located in the city of Toronto, Ontario, Canada, and is considered the signature icon of the city; more than two million international visitors are attracted annually to the tower. The CN Tower consists of several substructures. The main portion of the Tower consists of a hollow concrete pillar containing the elevators, stairwells and power and plumbing connections. On top is the 102 m (335 ft) metal broadcast antenna, carrying TV and radio signals. There are two main visitor areas, the main seven-story pod located at the 330 m (1,100 ft) level, and the SkyPod at 447 m (1,465 ft), just below the antenna. Microwave antennas ring the lower portion of the main pod, protected in a large white donut-shaped radome.

The Sky Pod, situated high above the main observation floor, is the highest public observation deck in the world. From its top, it is possible on a clear day to see approximately 100-120 km (62-74 mi) away and even see an outline of the city of Rochester across Lake Ontario in the United States, or the mist rising from Niagara Falls.

At 342 m (1,122 ft) is the Glass Floor and Outdoor Observation Deck. The Glass Floor is 23.8 m² (256 sq ft) and can withstand a pressure of 4,100 kPa (600 lbs/ in², 42 kg / cm²). The glass floor consists of thermal glass units that are 64 mm (2½ in) thick, consisting of a pane of 25 mm (1 in) laminated glass, a 25 mm (1 in) airspace and a pane of 13 mm (½ in) laminated glass. Some people experience vertigo by walking out on the glass floor and looking down at the ground below. (from wikipedia and
