Argo: lessons in planning?

I'm reading the new Tony Mendez book called Argo.  The Ben Affleck movie based on the book comes out soon.  Mendez, a former CIA agent, describes the amazing rescue of six diplomats from Tehran in 1980, after they had remained hidden and protected by the Canadian embassy while so many Americans were held hostage in Iran.  I think the book offers some interesting lessons in planning and preparation.  The plan was creative and bold, yet they prepared for many scenarios.  It was careful AND creative, meticulous AND adventurous.  I recommend the book and look forward to the movie.
