Steve Coll finds out at long last that the 9/11 mastermind visited the US, in 1979. It's detailed in a forthcoming book by Osama’s first wife, Najwa Bin Laden, and his son Omar Bin Laden. An excerpt:

I came to believe that Americans were gentle and nice, people easy to deal with. As far as the country itself goes, my husband and I did not hate America, yet we did not love it.

There was one incident that reminded me that some Americans are unaware of other cultures. When the time came for us to leave America, Osama and I, along with our two boys, waited for our departure at the airport in Indiana. I was sitting quietly in my chair, relaxing, grateful that our boys were quiet….

I saw an American man gawking at me. I knew without asking that his unwelcome attention had been snagged by my black Saudi costume…

I took a side glance at Osama and saw that he was intently studying the curious man. I knew that my husband would never allow the man to approach me…

When my husband and I discussed the incident, we were both more amused than offended. That man gave us a good laugh, as it was clear he had no knowledge of veiled women…

We returned to Saudi Arabia none the worse for our experiences.
