I also hear an E at the Olympic opening ceremony, though the bell is cast to be a B. 
Our friends in Nederland informs that the bell was tuned by Eijsbouts. Here is the video where this happens: http://www.youtube.com/watch?v=3d_USV1vSCo 
Many familiar faces. They do hit the bell once or twice in the video while tuning, during this it  has tones closer to the B. 
If Eijsbouts happened to create a tuning that produces a loud difference tone ("ghost tone"), all the expensive measuring tools shown in the video will not be able to detect it, only the human ear (or actually brain) can do that.  Thereafter simple math based on the partials -that create this tone and that can be measured- will confirm this.
