I saw it in Ottawa, it did a low circle around Parliament Hill - I think it was 1981. They had taken the entire assembly (the demonstrator, non-launch Enterprise) to the Paris Air Show and stopped over in Ottawa on the way back.
These replies are fantastic! Keep them coming. Now it appears Canadarm may be the winner, because, also crazy awesome! Who doesn’t want to play with the controls of that? Anyone over the age of six months does.
For my personal decoding story, I had a baby sitter when my sisters were too young (9&11) and they had Girl Scouts and whatever. 
So my sitter had to wake them up to figure out what in the world “rye pickets” was. I kept begging for rye pickets. When the sitter asked my sleeping sisters said (in unison) “RICE KRISPIES!!”
When my first daughter was just starting to talk she got a cold. She went to wipe her nose on something inappropriate I told her to stop and I would get her a Kleenex. At bedtime I gave her another one. The next day she asked me for an ‘X.’ I was confused for a minute until I realized she had heard “clean X.” For about a year she always wanted an ‘X’ at bedtime.
My first granddaughter at about the same age started using the word “bagah.” No one could figure out what she was saying, and she pointed at a just-removed dirty diaper and said, “bagah,” so we interpreted the word as meaning “shit.” That made for a nice euphemism for the whole family, as in “Oh, bagah, I spilled my soda.” Somebody finally realized that she was trying to say “garbage” and was reversing the syllables.
