The Valiant Air Command has announced that they have a P-47 coming to the airshow, which I believe is the first time a Thunderbolt will be attendance. They have also announced that a P-40, B-25, C-46 & F-4U Corsair will be attendance. Sounds like a great line-up.
The History Flight has released the 2012 tour schedule for their B-25, AT-6 and Stearman. Dates can be found here.
