U-2 Locations
I believe the latest designation of the plane is a TU-2S.
The fire crews on site at Sutter Buttes were told over the radio not to approach the wreckage due to the danger of a hydrogen [sic] leak. Reminds me of the SR-71 crash 50 years ago where Lockheed test pilot Bill Weaver famously advised a rancher in a helicopter, Albert Mitchell, Jr., to stay away from the wreck because there was a nuke weapon onboard.
