B-57 returned to original configuration:

Crews at the National Museum of the Air Force in Dayton, Ohio have restored a Vietnam War-era B-57 Martin Canberra and returned it to the museum's Southeast Asia War exhibit. Museum staff converted it from its EB-57 electronic countermeasures configuration used in the Vermont National Guard by reinstalling the weapons bay, removing antennae, and repainting it.
