In honor of the 70th anniversary of the Doolittle Raid, the National Museum of the USAF hosted a spectacle unlike any other in the warbird community. Along with a reunion of the last living members of the Doolittle outfit, the museum also played host to dozens of B-25s!
Here is a video of the mass formation fly-over in honor of the Raiders, finishing it off with Missing Man formation.
