Wow talk about ego... pity he can't give proper credit for The Canadian Caper (official name of the misson to extract the six US embassy workers) to the Canadian ambassador Ken Taylor and Canadian immigration officer John Sheadon and their wives Patricia Taylor and Zena Sheardon, for the primary role that they played in keeping the six Americans safe and getting them the passports to get out.
Seardon and his wife housed the six Americans for much of the time. They did not hold diplomatic immunity and were at the greatest risk for their roles. They received the Order of Canada for their role. The Taylors also received the Order of Canada and Ken Taylor was awarded the Congressional Gold Medal by the US.
Tony Mendez played a critical role, but he did not do it on his own and while his extraction story line was used, it was not the only one in play at the time.
The journalist who discovered the plan was Jean Pelltier the Washington correspondent for Montreal's La Presse. He refused to allow the paper to publish the story until confirmation was received that everyone was safely out.
